Legal Research Strategy

Preliminary analysis, organization, secondary sources, primary sources, updating research, identifying an end point, getting help, about this guide.

This guide will walk a beginning researcher though the legal research process step-by-step. These materials are created with the 1L Legal Research & Writing course in mind. However, these resources will also assist upper-level students engaged in any legal research project.

How to Strategize

Legal research must be comprehensive and precise.  One contrary source that you miss may invalidate other sources you plan to rely on.  Sticking to a strategy will save you time, ensure completeness, and improve your work product.

Understanding the Legal Questions

A legal question often originates as a problem or story about a series of events. In law school, these stories are called fact patterns. In practice, facts may arise from a manager or an interview with a potential client. Start by doing the following:

Read > Analyze > Assess > Note > Generate

  • Read anything you have been given
  • Analyze the facts and frame the legal issues
  • Assess what you know and need to learn
  • Note the jurisdiction and any primary law you have been given
  • Generate potential search terms

Jurisdiction

Legal rules will vary depending on where geographically your legal question will be answered. You must determine the jurisdiction in which your claim will be heard. These resources can help you learn more about jurisdiction and how it is determined:

  • Legal Treatises on Jurisdiction
  • LII Wex Entry on Jurisdiction

Getting Started

Once you have begun your research, you will need to keep track of your work. Logging your research will help you to avoid missing sources and explain your research strategy. You will likely be asked to explain your research process when in practice. Researchers can keep paper logs, folders on Westlaw or Lexis, or online citation management platforms.

Organizational Methods

Tracking with paper or excel.

Many researchers create their own tracking charts.  Be sure to include:

  • Search Date
  • Topics/Keywords/Search Strategy
  • Citation to Relevant Source Found
  • Save Locations
  • Follow Up Needed

Consider using the following research log as a starting place: 

  • Sample Research Log

Tracking with Folders

Westlaw and Lexis offer options to create folders, then save and organize your materials there.

  • Lexis Advance Folders
  • Westlaw Edge Folders

Tracking with Citation Management Software

For long term projects, platforms such as Zotero, EndNote, Mendeley, or Refworks might be useful. These are good tools to keep your research well organized. Note, however, that none of these platforms substitute for doing your own proper Bluebook citations. Learn more about citation management software on our other research guides:

Types of Sources

There are three different types of sources: Primary, Secondary, and Tertiary.  When doing legal research you will be using mostly primary and secondary sources.  We will explore these different types of sources in the sections below.

Graph Showing Types of Legal Research Resources.  Tertiary Sources: Hollis, Law Library Website.  Secondary Sources:  Headnotes & Annotations, American Law Reports, Treatises, Law Reviews & Journals, Dictionaries and Encyclopedias, Restatements.  Primary Sources: Constitutions, Treatises, Statutes, Regulations, Case Decisions, Ordinances, Jury Instructions.

Secondary sources often explain legal principles more thoroughly than a single case or statute. Starting with them can help you save time.

Secondary sources are particularly useful for:

  • Learning the basics of a particular area of law
  • Understanding key terms of art in an area
  • Identifying essential cases and statutes

Consider the following when deciding which type of secondary source is right for you:

  • Scope/Breadth
  • Depth of Treatment
  • Currentness/Reliability

Chart Illustrating Depth and Breadth of Secondary Sources by Type.  Legal Dictionaries (Shallow and Broad), Legal Encyclopedias (Shallow and Broad), Restatements (Moderately Deep and Broad), Treatises (Moderately Deep and Moderately Narrow), American Law Reports (Extremely Deep and Extremely Narrow), Law Journal Articles (Extremely Deep and Extremely Narrow)

Legal Dictionaries & Encyclopedias

Legal dictionaries.

Legal dictionaries are similar to other dictionaries that you have likely used before.

  • Black's Law Dictionary
  • Ballentine's Law Dictionary

Legal Encyclopedias

Legal encyclopedias contain brief, broad summaries of legal topics, providing introductions and explaining terms of art. They also provide citations to primary law and relevant major law review articles.  

Graph illustrating that Legal Encyclopedias have broad coverage of subject matter and content with shallow treatment of the topics.

Here are the two major national encyclopedias:

  • American Jurisprudence (AmJur) (Westlaw)
  • American Jurisprudence (Lexis)
  • Corpus Juris Secundum (CJS)

Treatises are books on legal topics.  These books are a good place to begin your research.  They provide explanation, analysis, and citations to the most relevant primary sources. Treatises range from single subject overviews to deep treatments of broad subject areas.

Graph illustrating that Treatises are moderate in scope and relatively deep.

It is important to check the date when the treatise was published. Many are either not updated, or are updated through the release of newer editions.

To find a relevant treatise explore:

  • Legal Treatises by Subject by Catherine Biondo Last Updated Apr 12, 2024 6029 views this year

American Law Reports (ALR)

American Law Reports (ALR) contains in-depth articles on narrow topics of the law. ALR articles, are often called annotations. They provide background, analysis, and citations to relevant cases, statutes, articles, and other annotations. ALR annotations are invaluable tools to quickly find primary law on narrow legal questions.

Graph illustrating that American Law Reports are narrow in scope but treat concepts deeply.

This resource is available in both Westlaw and Lexis:

  • American Law Reports on Westlaw (includes index)
  • American Law Reports on Lexis

Law Reviews & Journals

Law reviews are scholarly publications, usually edited by law students in conjunction with faculty members. They contain both lengthy articles and shorter essays by professors and lawyers. They also contain comments, notes, or developments in the law written by law students. Articles often focus on new or emerging areas of law and may offer critical commentary. Some law reviews are dedicated to a particular topic while others are general. Occasionally, law reviews will include issues devoted to proceedings of panels and symposia.

Graph illustrating that Law Review and Journal articles are extremely narrow in scope but exceptionally deep.

Law review and journal articles are extremely narrow and deep with extensive references. 

To find law review articles visit:

  • Law Journal Library on HeinOnline
  • Law Reviews & Journals on LexisNexis
  • Law Reviews & Journals on Westlaw

Restatements

Restatements are highly regarded distillations of common law, prepared by the American Law Institute (ALI). ALI is a prestigious organization comprised of judges, professors, and lawyers. They distill the "black letter law" from cases to indicate trends in common law. Resulting in a “restatement” of existing common law into a series of principles or rules. Occasionally, they make recommendations on what a rule of law should be.

Restatements are not primary law. However, they are considered persuasive authority by many courts.

Graph illustrating that Restatements are broad in scope and treat topics with moderate depth.

Restatements are organized into chapters, titles, and sections.  Sections contain the following:

  • a concisely stated rule of law,
  • comments to clarify the rule,
  • hypothetical examples,
  • explanation of purpose, and
  • exceptions to the rule  

To access restatements visit:

  • American Law Institute Library on HeinOnline
  • Restatements & Principles of the Law on LexisNexis
  • Restatements & Principles of Law on Westlaw

Primary Authority

Primary authority is "authority that issues directly from a law-making body."   Authority , Black's Law Dictionary (11th ed. 2019).   Sources of primary authority include:

  • Constitutions
  • Statutes 

Regulations

Access to primary legal sources is available through:

  • Bloomberg Law
  • Free & Low Cost Alternatives

Statutes (also called legislation) are "laws enacted by legislative bodies", such as Congress and state legislatures.  Statute , Black's Law Dictionary (11th ed. 2019).

We typically start primary law research here. If there is a controlling statute, cases you look for later will interpret that law. There are two types of statutes, annotated and unannotated.

Annotated codes are a great place to start your research. They combine statutory language with citations to cases, regulations, secondary sources, and other relevant statutes. This can quickly connect you to the most relevant cases related to a particular law. Unannotated Codes provide only the text of the statute without editorial additions. Unannotated codes, however, are more often considered official and used for citation purposes.

Case Basics

In many areas, finding relevant caselaw will comprise a significant part of your research. This Is particularly true in legal areas that rely heavily on common law principles.

Running Time: 3 minutes, 10 seconds.

Unpublished Cases

Up to  86% of federal case opinions are unpublished. You must determine whether your jurisdiction will consider these unpublished cases as persuasive authority. The Federal Rules of Appellate Procedure have an overarching rule, Rule 32.1  Each circuit also has local rules regarding citations to unpublished opinions. You must understand both the Federal Rule and the rule in your jurisdiction.

  • Federal and Local Rules of Appellate Procedure 32.1 (Dec. 2021).
  • Type of Opinion or Order Filed in Cases Terminated on the Merits, by Circuit (Sept. 2021).

Each state also has its own local rules which can often be accessed through:

  • State Bar Associations
  • State Courts Websites

First Circuit

  • First Circuit Court Rule 32.1.0

Second Circuit

  • Second Circuit Court Rule 32.1.1

Finding Cases

Image of a Headnote in a Print Reporter

Headnotes show the key legal points in a case. Legal databases use these headnotes to guide researchers to other cases on the same topic. They also use them to organize concepts explored in cases by subject. Publishers, like Westlaw and Lexis, create headnotes, so they are not consistent across databases.

Headnotes are organized by subject into an outline that allows you to search by subject. This outline is known as a "digest of cases." By browsing or searching the digest you can retrieve all headnotes covering a particular topic. This can help you identify particularly important cases on the relevant subject.

Running Time: 4 minutes, 43 seconds.

Each major legal database has its own digest:

  • Topic Navigator (Lexis)
  • Key Digest System (Westlaw)

Start by identifying a relevant topic in a digest.  Then you can limit those results to your jurisdiction for more relevant results.  Sometimes, you can keyword search within only the results on your topic in your jurisdiction.  This is a particularly powerful research method.

One Good Case Method

After following the steps above, you will have identified some relevant cases on your topic. You can use good cases you find to locate other cases addressing the same topic. These other cases often apply similar rules to a range of diverse fact patterns.

  • in Lexis click "More Like This Headnote"
  • in Westlaw click "Cases that Cite This Headnote"

to focus on the terms of art or key words in a particular headnote. You can use this feature to find more cases with similar language and concepts.  ​

Ways to Use Citators

A citator is "a catalogued list of cases, statutes, and other legal sources showing the subsequent history and current precedential value of those sources.  Citators allow researchers to verify the authority of a precedent and to find additional sources relating to a given subject." Citator , Black's Law Dictionary (11th ed. 2019).

Each major legal database has its own citator.  The two most popular are Keycite on Westlaw and Shepard's on Lexis.

Using Citators For

Citators serve three purposes: (1) case validation, (2) better understanding, and (3) additional research.

Case Validation

Is my case or statute good law?

  • Parallel citations
  • Prior and subsequent history
  • Negative treatment suggesting you should no longer cite to holding.

Better Understanding

Has the law in this area changed?

  • Later cases on the same point of law
  • Positive treatment, explaining or expanding the law.
  • Negative Treatment, narrowing or distinguishing the law.

Track Research

Who is citing and writing about my case or statute?

  • Secondary sources that discuss your case or statute.
  • Cases in other jurisdictions that discuss your case or statute.

How to do legal research in 3 steps

Knowing where to start a difficult legal research project can be a challenge. But if you already understand the basics of legal research, the process can be significantly easier — not to mention quicker.

Solid research skills are crucial to crafting a winning argument. So, whether you are a law school student or a seasoned attorney with years of experience, knowing how to perform legal research is important — including where to start and the steps to follow.

What is legal research, and where do I start? 

Black's Law Dictionary defines legal research as “[t]he finding and assembling of authorities that bear on a question of law." But what does that actually mean? It means that legal research is the process you use to identify and find the laws — including statutes, regulations, and court opinions — that apply to the facts of your case.

In most instances, the purpose of legal research is to find support for a specific legal issue or decision. For example, attorneys must conduct legal research if they need court opinions — that is, case law — to back up a legal argument they are making in a motion or brief filed with the court.

Alternatively, lawyers may need legal research to provide clients with accurate legal guidance . In the case of law students, they often use legal research to complete memos and briefs for class. But these are just a few situations in which legal research is necessary.

Why is legal research hard?

Each step — from defining research questions to synthesizing findings — demands critical thinking and rigorous analysis.

1. Identifying the legal issue is not so straightforward. Legal research involves interpreting many legal precedents and theories to justify your questions. Finding the right issue takes time and patience.

2. There's too much to research. Attorneys now face a great deal of case law and statutory material. The sheer volume forces the researcher to be efficient by following a methodology based on a solid foundation of legal knowledge and principles.

3. The law is a fluid doctrine. It changes with time, and staying updated with the latest legal codes, precedents, and statutes means the most resourceful lawyer needs to assess the relevance and importance of new decisions.

Legal research can pose quite a challenge, but professionals can improve it at every stage of the process . 

Step 1: Key questions to ask yourself when starting legal research

Before you begin looking for laws and court opinions, you first need to define the scope of your legal research project. There are several key questions you can use to help do this.

What are the facts?

Always gather the essential facts so you know the “who, what, why, when, where, and how” of your case. Take the time to write everything down, especially since you will likely need to include a statement of facts in an eventual filing or brief anyway. Even if you don't think a fact may be relevant now, write it down because it may be relevant later. These facts will also be helpful when identifying your legal issue.

What is the actual legal issue?

You will never know what to research if you don't know what your legal issue is. Does your client need help collecting money from an insurance company following a car accident involving a negligent driver? How about a criminal case involving excluding evidence found during an alleged illegal stop?

No matter the legal research project, you must identify the relevant legal problem and the outcome or relief sought. This information will guide your research so you can stay focused and on topic.

What is the relevant jurisdiction?

Don't cast your net too wide regarding legal research; you should focus on the relevant jurisdiction. For example, does your case deal with federal or state law? If it is state law, which state? You may find a case in California state court that is precisely on point, but it won't be beneficial if your legal project involves New York law.

Where to start legal research: The library, online, or even AI?

In years past, future attorneys were trained in law school to perform research in the library. But now, you can find almost everything from the library — and more — online. While you can certainly still use the library if you want, you will probably be costing yourself valuable time if you do.

When it comes to online research, some people start with free legal research options , including search engines like Google or Bing. But to ensure your legal research is comprehensive, you will want to use an online research service designed specifically for the law, such as Westlaw . Not only do online solutions like Westlaw have all the legal sources you need, but they also include artificial intelligence research features that help make quick work of your research

Step 2: How to find relevant case law and other primary sources of law

Now that you have gathered the facts and know your legal issue, the next step is knowing what to look for. After all, you will need the law to support your legal argument, whether providing guidance to a client or writing an internal memo, brief, or some other legal document.

But what type of law do you need? The answer: primary sources of law. Some of the more important types of primary law include:

  • Case law, which are court opinions or decisions issued by federal or state courts
  • Statutes, including legislation passed by both the U.S. Congress and state lawmakers
  • Regulations, including those issued by either federal or state agencies
  • Constitutions, both federal and state

Searching for primary sources of law

So, if it's primary law you want, it makes sense to begin searching there first, right? Not so fast. While you will need primary sources of law to support your case, in many instances, it is much easier — and a more efficient use of your time — to begin your search with secondary sources such as practice guides, treatises, and legal articles.

Why? Because secondary sources provide a thorough overview of legal topics, meaning you don't have to start your research from scratch. After secondary sources, you can move on to primary sources of law.

For example, while no two legal research projects are the same, the order in which you will want to search different types of sources may look something like this:

  • Secondary sources . If you are researching a new legal principle or an unfamiliar area of the law, the best place to start is secondary sources, including law journals, practice guides , legal encyclopedias, and treatises. They are a good jumping-off point for legal research since they've already done the work for you. As an added bonus, they can save you additional time since they often identify and cite important statutes and seminal cases.
  • Case law . If you have already found some case law in secondary sources, great, you have something to work with. But if not, don't fret. You can still search for relevant case law in a variety of ways, including running a search in a case law research tool.

Once you find a helpful case, you can use it to find others. For example, in Westlaw, most cases contain headnotes that summarize each of the case's important legal issues. These headnotes are also assigned a Key Number based on the topic associated with that legal issue. So, once you find a good case, you can use the headnotes and Key Numbers within it to quickly find more relevant case law.

  • Statutes and regulations . In many instances, secondary sources and case law list the statutes and regulations relevant to your legal issue. But if you haven't found anything yet, you can still search for statutes and regs online like you do with cases.

Once you know which statute or reg is pertinent to your case, pull up the annotated version on Westlaw. Why the annotated version? Because the annotations will include vital information, such as a list of important cases that cite your statute or reg. Sometimes, these cases are even organized by topic — just one more way to find the case law you need to support your legal argument.

Keep in mind, though, that legal research isn't always a linear process. You may start out going from source to source as outlined above and then find yourself needing to go back to secondary sources once you have a better grasp of the legal issue. In other instances, you may even find the answer you are looking for in a source not listed above, like a sample brief filed with the court by another attorney. Ultimately, you need to go where the information takes you.

Step 3: Make sure you are using ‘good’ law

One of the most important steps with every legal research project is to verify that you are using “good" law — meaning a court hasn't invalidated it or struck it down in some way. After all, it probably won't look good to a judge if you cite a case that has been overruled or use a statute deemed unconstitutional. It doesn't necessarily mean you can never cite these sources; you just need to take a closer look before you do.

The simplest way to find out if something is still good law is to use a legal tool known as a citator, which will show you subsequent cases that have cited your source as well as any negative history, including if it has been overruled, reversed, questioned, or merely differentiated.

For instance, if a case, statute, or regulation has any negative history — and therefore may no longer be good law — KeyCite, the citator on Westlaw, will warn you. Specifically, KeyCite will show a flag or icon at the top of the document, along with a little blurb about the negative history. This alert system allows you to quickly know if there may be anything you need to worry about.

Some examples of these flags and icons include:

  • A red flag on a case warns you it is no longer good for at least one point of law, meaning it may have been overruled or reversed on appeal.
  • A yellow flag on a case warns that it has some negative history but is not expressly overruled or reversed, meaning another court may have criticized it or pointed out the holding was limited to a specific fact pattern.
  • A blue-striped flag on a case warns you that it has been appealed to the U.S. Supreme Court or the U.S. Court of Appeals.
  • The KeyCite Overruling Risk icon on a case warns you that the case may be implicitly undermined because it relies on another case that has been overruled.

Another bonus of using a citator like KeyCite is that it also provides a list of other cases that merely cite your source — it can lead to additional sources you previously didn't know about.

Perseverance is vital when it comes to legal research

Given that legal research is a complex process, it will likely come as no surprise that this guide cannot provide everything you need to know.

There is a reason why there are entire law school courses and countless books focused solely on legal research methodology. In fact, many attorneys will spend their entire careers honing their research skills — and even then, they may not have perfected the process.

So, if you are just beginning, don't get discouraged if you find legal research difficult — almost everyone does at first. With enough time, patience, and dedication, you can master the art of legal research.

The position of legal studies has increasingly become part of a debate among legal scholars and their university colleagues in disciplines like economics, sociology, political sciences, psychology, history and linguistics. This shift has gone hand in hand with internationalisation, Europeanisation and globalisation processes over the last 30 years. The legal scholars' playing field as well as the rules of the game, the methodology, have both changed tremendously, and that change has triggered a long overdue debate about methodology in legal studies.

A central issue of writing a doctoral thesis is the methodology, as it describes the broad theoretical and philosophical underpinning to the chosen research methods. Methodology is closely related to what we understand the field of enquiry (i.e., international or EU law) to be and it guides our thinking or questioning of, or within, that field or both. The study employs the problem-based theory and qualitative doctrinal legal research methodology.

The researcher may be interested in legal behaviour, rules, processes, or problems about which little is known or understood: Chui ( 2007 ), p. 50.

Typical research questions of descriptive research designs are: What is happening? How is something happening? What has happened? Ibid.

Wasastjerna ( 2020 ), p. 21; Hervey et al. ( 2011 ).

‘What’, ‘when’, ‘who’ and ‘where’ questions seek descriptive answers; ‘why’ questions seek understanding and explanation; and ‘how’ questions seek appropriate interventions to bring about change: Blaikie ( 2003 ), p. 13.

Ibid. p. 10.

Doctrinal research has been considered by some scholars as less compelling or respected than the research methods used by those in the sciences and social sciences. However, valid research is built on sound foundations, so before embarking on any theoretical critique of the law or empirical study about the law in operation, it is incumbent on the researcher to verify the authority and status of the legal doctrine being examined: Ibid. pp. 7–8.

Quantitative research deals with numbers, statistics or hard data whereas qualitative data are mostly in the form of words. Qualitative researchers tend to be more flexible than their quantitative counterparts in terms of the structure to research. In contrast to empirical research, doctrinal research, which ‘is library-based’, focusing on a reading and analysis of the regarded as the most accepted research paradigm: Hutchinson ( 2013 ), p. 7.

Dobinson and Johns ( 2007 ), p. 40.

Ibid. p. 20.

Such research might begin by collecting all relevant case law in order to demonstrate how a particular law is not working. Alternatively, a researcher may observe a number of cases to assess whether there are existing procedural problems in the way in which certain parts of a trial are carried out. Based on this, the researcher could reach a tentative conclusion that the current law needs amendment, repeal, or there is a need for new law. Problem, policy and law reform research often includes a consideration of the social factors involved and/or the social impact of current law and practice. In this regard, the type of research done might include surveys and interviews with various individuals and groups affected. Such research is often referred to as socio-legal research: Ibid.

Valdani ( 2019 ), p. 14.

Dobinson and Johns ( 2007 ), p. 41.

Ibid.; This research design, to some extent, mirrors that of a social science study, but with one important exception. The information or data collected is not quantifiable, but rather it is legislation and case law as well as relevant secondary commentary. As a result, the information-based or ‘library-based’ research design, which is often directed to identifying the resolution to a specific legal problem, has had a detrimental effect on the status of the doctrinal methodology the broader (interdisciplinary) academic context. Therefore, some argue that the doctrinal methodology is simply ‘legal puzzle solving’, and little more than a process used in order to achieve pragmatic solutions. Hutchinson ( 2013 ), p. 7.

Literature review is defined as being ‘a systematic, explicit and reproducible method for identifying, evaluating and synthesising the existing body of completed and recorded work produced by researchers, scholars and practitioners’: Fink ( 2019 ), p. 3.

The comparative approach is mostly visible in Chap. 6 where the Finland and France MaaS data sharing are compared.

Infographics provide an engaging visual display communication tool that offers to researchers the ability to present intense and sophisticated information on a certain subject in a more comprehensible manner: Dur ( 2014 ), pp. 39–50.

Much has been written about MaaS – from multiple and sometimes conflicting perspectives. ITF ( 2021 ), p. 4.

This guide contains resources to help students researching and writing a legal dissertation or other upper-level writing project. Some of the resources in this guide are directed at researching and writing in general, not specifically on legal topics, but the strategies and tips can still be applied.

The Law Library maintains a number of other guides on related skills and topics that may be of interest:

The Wells Library also maintains guides. A few that may be helpful for managing research can be found here:

Choosing a Topic

This video discusses tips and strategies for choosing a dissertation topic.

Note: this video is not specific to legal dissertation topics, but it may still be of interest as an overview generally.

The Bloomberg/BNA publication United States Law Week can be a helpful resource for tracking down the major legal stories of the day.  Log into Bloomberg Law, in the big search box, start typing United States Law Week and the title will appear in the drop down menu beneath the box. This publication provides coverage of top legal news stories, and in-depth "insight" features.

If you have a general idea of the area of law you wish to write about, check out the Practice Centers on Bloomberg. From the homepage, click the Browse link in the top left-hand corner. Then select Practice Centers and look for your area of law. Practice Centers are helpful because they gather cases, statutes, administrative proceedings, news, and more on the selected legal area.

Bloomberg has other news sources available as well. From the homepage, click the Browse link in the top left-hand corner. Then select News and Analysis, then select News or Analysis, and browse the available topics.

If you know what area of law you'd like to write about, you may find the Browse Topics feature in Lexis Advance helpful for narrowing down your topic. 

Log into Lexis Advance, click the Browse Topics tab, and select a topic.  If you don't see your topic listed, try using the provided search bar to see whether your topic is categorized as a sub-topic within this list. 

Once you click on a topic, a box pops up with several options.  If you click on Get Topic Document, you'll see results listed in a number of categories, including Cases, Legislation, and more.  The News and Legal News categories at the right end of the list may help you identify current developments of interest for your note.  Don't forget about the filtering options on the left that will allow you to search within your results, narrow your jurisdiction, and more.

Similar to Lexis Advance, Westlaw Edge has a Topics tab that may be helpful if you know what area of law you'd like to write about.

Log onto Westlaw Edge, and click on the Topics tab.  This time, you won't be able to search within this list, so if you're area is not listed, you should either run a regular search from the main search bar at the top or try out some of the topics listed under this tab - once you click on a topic, you can search within its contents.

What is great about the Topics in Westlaw Edge is the Practitioner Insights page you access by clicking on a topic.  This is an information portal that allows you quick access to cases, legislation, top news, and more on your selected topic.

In United States federal courts, a circuit split occurs whenever two or more circuit courts of appeals issue conflicting rulings on the same legal question. Circuit splits are ripe for legal analysis and commentary because they present a situation in which federal law is being applied in different ways in different parts of the country, even if the underlying litigants themselves are otherwise similarly situated. The Supreme Court also frequently accepts cases on appeal that involve these types of conflicted rulings from various sister circuits.

To find a circuit split on a topic of interest to you, try searching on Lexis and Westlaw using this method:

in the search box, enter the following: (circuit or court w/s split) AND [insert terms or phrases to narrow the search]

You can also browse for circuit splits on Bloomberg. On the Bloomberg homepage, in the "Law School Success" box, Circuit Splits Charts appear listed under Secondary Sources.

Other sources for circuit splits are American Law Reports (ALR) and American Jurisprudence (AmJur). These publications provide summaries of the law, point out circuit splits, and provide references for further research.

"Blawgs" or law-related blogs are often written by scholars or practitioners in the legal field.  Ordinarily covering current events and developments in law, these posts can provide inspiration for note topics.  To help you find blawgs on a specific topic, consider perusing the ABA's Blawg Directory or Justia's Blawg Search .

Research Methodology

Types of research methodologies.

There are different types of research methodologies. Methodology refers to the strategy employed in conducting research. The following methodologies are some of the most commonly used in legal and social science research.

Doctrinal legal research methodology, also called "black letter" methodology, focuses on the letter of the law rather than the law in action. Using this method, a researcher composes a descriptive and detailed analysis of legal rules found in primary sources (cases, statutes, or regulations). The purpose of this method is to gather, organize, and describe the law; provide commentary on the sources used; then, identify and describe the underlying theme or system and how each source of law is connected.

Doctrinal methodology is good for areas of law that are largely black letter law, such as contract or property law. Under this approach, the researcher conducts a critical, qualitative analysis of legal materials to support a hypothesis. The researcher must identify specific legal rules, then discuss the legal meaning of the rule, its underlying principles, and decision-making under the rule (whether cases interpreting the rule fit together in a coherent system or not). The researcher must also identify ambiguities and criticisms of the law, and offer solutions. Sources of data in doctrinal research include the rule itself, cases generated under the rule, legislative history where applicable, and commentaries and literature on the rule.

This approach is beneficial by providing a solid structure for crafting a thesis, organizing the paper, and enabling a thorough definition and explanation of the rule. The drawbacks of this approach are that it may be too formalistic, and may lead to oversimplifying the legal doctrine.

Comparative

Comparative legal research methodology involves critical analysis of different bodies of law to examine how the outcome of a legal issue could be different under each set of laws. Comparisons could be made between different jurisdictions, such as comparing analysis of a legal issue under American law and the laws of another country, or researchers may conduct historical comparisons.

When using a comparative approach be sure to define the reasons for choosing this approach, and identify the benefits of comparing laws from different jurisdictions or time periods, such as finding common ground or determining best practices and solutions. The comparative method can be used by a researcher to better understand their home jurisdiction by analyzing how other jurisdictions handle the same issue. This method can also be used as a critical analytical tool to distinguish particular features of a law. The drawback of this method is that it can be difficult to find material from other jurisdictions. Also, researchers should be sure that the comparisons are relevant to the thesis and not just used for description.

This type of research uses data analysis to study legal systems. A detailed guide on empirical methods can be found here . The process of empirical research involves four steps: design the project, collect and code the data, analyze the data, determine best method of presenting the results. The first step, designing the project, is when researchers define their hypothesis and concepts in concrete terms that can be observed. Next, researchers must collect and code the data by determining the possible sources of information and available collection methods, and then putting the data into a format that can be analyzed. When researchers analyze the data, they are comparing the data to their hypothesis. If the overlap between the two is significant, then their hypothesis is confirmed, but if there is little to no overlap, then their hypothesis is incorrect. Analysis involves summarizing the data and drawing inferences. There are two types of statistical inference in empirical research, descriptive and causal. Descriptive inference is close to summary, but the researcher uses the known data from the sample to draw conclusions about the whole population. Causal inference is the difference between two descriptive inferences.

Two main types of empirical legal research are qualitative and quantitative.

Quantitative, or numerical, empirical legal research involves taking information about cases and courts, translating that information into numbers, and then analyzing those numbers with statistical tools.

Qualitative, or non-numerical, empirical legal research involves extracting  information from the text of court documents, then interpreting and organizing the text into categories, and using that information to identify patterns.

Drafting The Methodology Section

This is the part of your paper that describes the research methodology, or methodologies if you used more than one. This section will contain a detailed description of how the research was conducted and why it was conducted in that way. First, draft an outline of what you must include in this section and gather the information needed.

Generally, a methodology section will contain the following:

  • Statement of research objectives
  • Reasons for the research methodology used
  • Description and rationale of the data collection tools, sampling techniques, and data sources used, including a description of how the data collection tools were administered
  • Discussion of the limitations
  • Discussion of the data analysis tools used

Be sure that you have clearly defined the reasoning behind the chosen methodology and sources.

Literature Review

The literature review provides an examination of existing pieces of research, and serves as a foundation for further research. It allows the researcher to critically evaluate existing scholarship and research practices, and puts the new thesis in context. When conducting a literature review, one should consider the following: who are the leading scholars in the subject area; what has been published on the subject; what factors or subtopics have these scholars identified as important for further examination; what research methods have others used; what were the pros and cons of using those methods; what other theories have been explored.

The literature review should include a description of coverage. The researcher should describe what material was selected and why, and how those selections are relevant to the thesis. Discuss what has been written on the topic and where the thesis fits in the context of existing scholarship. The researcher should evaluate the sources and methodologies used by other researchers, and describe how the thesis different.

The following video gives an overview of conducting a literature review.

Note: this video is not specific to legal literature, however it may be helpful as a general overview.

Not sure where to start? Here are a few suggestions for digging into sources once you have selected a topic.

Research Guides

Research guides are discovery tools, or gateways of information. They pull together lists of sources on a topic. Some guides even offer brief overviews and additional research steps specifically for that topic. Many law libraries offer guides on a variety of subjects. You can locate guides by visiting library websites, such as this Library's site , the Law Library of Congress , or other schools like Georgetown . Some organizations also compile research guides, such as the American Society of International Law . Utilizing a research guide on your topic to generate an introductory source list can save you valuable time.

Secondary Sources

It is often a good idea to begin research with secondary sources. These resources summarize, explain, and analyze the law. They also provide references to primary sources and other secondary sources. This saves you time and effort, and can help you quickly identify major themes under your topic and help you place your thesis in context.

Encyclopedias provide broad coverage of all areas of the law, but do not go in-depth on narrow topics, or discuss differences by jurisdiction, or  include all of the pertinent cases. American Jurisprudence ( AmJur ) and Corpus Juris Secundum ( CJS ) have nationwide coverage, while the Indiana Law Encyclopedia focuses on Indiana state law. A number of other states also have their own state-specific encyclopedias.

American Law Reports ( ALR ) are annotations that synopsize various cases on narrow legal topics. Each annotation covers a different topic, and provides a leading or typical case on the topic, plus cases from different jurisdictions that follow different rules, or cases where different facts applying the same rule led to different outcomes. The annotations also refer to other secondary sources.  

Legal periodicals include several different types of publications such as law reviews from academic institutions or organizations, bar journals, and commercial journals/newspapers/newsletters. Legal periodicals feature articles that describe the current state of the law and often explore underlying policies. They also critique laws, court decisions, and policies, and often advocate for changes. Articles also discuss emerging issues and notify the profession of new developments. Law reviews can be useful for in-depth coverage on narrow topics, and references to primary and other secondary sources. However, content can become outdated and researchers must be mindful of biases in articles. 

Treatises/Hornbooks/Practice Guides are a type of secondary source that provides comprehensive coverage of a legal subject. It could be broad, such as a treatise covering all of contract law, or very narrow such as a treatise focused only on search and seizure cases. These sources are good when you have some general background on the topic, but you need more in-depth coverage of the legal rules and policies. Treatises are generally well organized, and provide you with finding aids (index, table of contents, etc.) and extensive footnotes or endnotes that will lead you to primary sources like cases, statutes, and regulations. They may also include appendices with supporting material like forms. However, treatises may not be updated as frequently as other sources and may not cover your specific issue or jurisdiction.

12 Qualitative Legal Research: A Methodological Discourse

  • Published: January 2020
  • Cite Icon Cite
  • Permissions Icon Permissions

Qualitative legal research aims to study things in their natural settings, understand and interpret their social realities and provide inputs on various aspects of social life. It focuses on people’s feelings, perceptions, and experiences. It differs from quantitative research in matters of nature of data, theoretical basis, and kinds of tools employed for data collection. The combination of two methods brings synergy. Worthy features of qualitative legal research consist of description of social setting, interpretation of social data, verification of assumptions, and evaluation of policies. Its steps include framing of specific questions, choice of data collection tools, sampling, data collection, analysis, and interpretation. This method allows for a mature understanding of the problematic world.

Priority Updates from the Research Literature (PURLs) is a product of the Family Practice Inquiries Network (FPIN) designed to alert practicing primary care clinicians about new discoveries that could cause them to change their practice. 1 The purpose of PURLs is to leverage an organized surveillance system to rapidly scan a large amount of medical literature relevant to primary care, identify the small percentage of that literature that represents a potential change in practice, complete a thorough review process to determine if it should change practice, and succinctly summarize that evidence for busy clinicians. 2 The purpose of this article is to illuminate the rigorous process by which FPIN identifies, evaluates, and publishes a PURL.

  • The PURLs Surveillance Team

The identification of a potential PURL starts with the PURLs Surveillance Team. This team is a group of highly motivated primary care clinicians interested in new research that could represent practice-changing findings. The team is led by an FPIN staff member and the PURLs Editor-in-Chief (EIC). Volunteers from this group agree to monitor over 20 medical journals that are likely to publish findings relevant to practicing family physicians. With a relatively small number of volunteers, a large amount of new primary care literature can be monitored on a regular basis. When one of these volunteers, or any member of the Surveillance Team, identifies a new article that they believe may represent a potential change in practice, they can nominate the article by posting the abstract along with their reasoning behind nominating it. The nomination is then commented on by the individual members of the PURLs Surveillance Team where members share their opinion on whether the article is a potential PURL. Based on the robust discussion by the PURLs Surveillance Team, the PURLs EIC makes a final determination as to whether the nominated article should continue forward in the process. If it is determined that it should move forward, it is noted as a potential PURL and prepared for an in-depth review by a PURL Jam Site.

  • PURL Jam Sessions

Potential PURLs are assigned to one of a handful of family medicine residencies (PURL Jam Sites) for systematic review at events called “PURL Jam Sessions.” PURL Jam Sites are members of FPIN who have gone through an application process with the PURLs EIC and have been approved based on their significant critical appraisal experience, faculty availability, and program buy-in. A PURL Jam Session is a highly structured and rigorous journal club. PURL Jams are led by a local expert in evidence-based medicine and include a small number of faculty and residents. In addition to a thorough evaluation of the article in question, PURL Jams represent a valuable learning experience for the participants as they practice critical appraisal of the literature. The PURL Jam Site utilizes a structured Potential PURL Review Form (PPRF) to evaluate each article. There are different PPRFs, with tailored questions to address the nuances of various study designs. The PPRF form provides a series of structured critical appraisal questions for the PURL Jam Site to consider, with the goal of determining whether or not the article is a “PURL.” An article can only be declared a PURL if it meets all 6 PURLs criteria, which are explained in Table 1 . Once the PPRF is completed, the PURL Jam Site prepares a Diving for PURL (DfP) manuscript that summarizes the article and includes an explanation for each PURL criteria. Both the PPRF and DfP manuscript are submitted to FPIN.

PURLs Criteria

  • First Round of Peer and Editorial Review

The PURLs EIC reviews the first draft and may request edits from the author team. Once the EIC is satisfied with the DfP manuscript, it is sent to the local expert at another PURL Jam Site for peer review. The PURLs EIC then reviews the peer reviewer’s feedback and asks the authors to incorporate pertinent feedback from the reviewer. If the author states the article met all 6 PURLs criteria, and the peer reviewer or PURLs EIC disagrees, the PURLs EIC makes the determination as to whether the manuscript will proceed as a PURL. If the PURLs EIC does not agree with the author that it is a PURL, the author will be asked to revise. If the manuscript does not meet all 6 PURLs criteria, it then proceeds to publication as a DfP in Evidence-Based Practice so readers can understand why the particular article may not result in a change in practice.

  • Second Round of Peer and Editorial Review

Once the PURLs EIC has approved the DfP manuscript and agrees the article is a PURL, the PURL Jam Site expands the DfP manuscript into a PURL manuscript and completes Speaker Notes. The PURL manuscript has additional components including the practice change, an illustrative case, clinical context, caveats, and potential challenges. Speaker Notes are a critical appraisal worksheet utilized in FPIN’s Journal Club product. Once the PURL Jam Site submits the PURL manuscript, it goes through an additional peer review. A PURL Deputy Editor then edits the manuscript, incorporates peer review feedback into the manuscript, and requests that the authors revise. If the peer reviewer does not agree that the article meets all 6 PURLs criteria, the PURLs Deputy Editor reviews their reasoning and determines whether they believe it meets all 6 PURLs criteria. If the PURL Deputy Editor does not think the article is a PURL, it is sent to FPIN’s Vice President of Publications to decide if the manuscript will continue as a PURL, or if the DfP will be published in Evidence-Based Practice instead. If the Vice President of Publications states it is a PURL, the manuscript will be revised by the authors and continue in the editorial review process. The PURL Deputy Editor reviews the authors’ revision and either requests additional edits or approves the PURL manuscript for publication.

  • Publication

Finalized PURL manuscripts are sent to a family medicine journal for publication. The PURLs format provides an easy-to-read synthesis of the standardized review process. Published PURLs review the evidence and explain why the findings are compelling enough to warrant providers changing their practice. The finalized PURL has been reviewed by at least 4 experts in the PURL methodology before the manuscript completing an additional round of peer review with the journal before final publication, which is represented by Figure 1 . The final product then has completed a rigorous evaluation process that includes the scrutiny of many PURL experts resulting in a brief, easy-to-read synopsis of the evidence for an immediate impact on patient care.
