How to Cite a Thesis or Dissertation in APA

In this citation guide, you will learn how to reference and cite an undergraduate thesis, master’s thesis, or doctoral dissertation. This guide will also review the differences between a thesis or dissertation that is published and one that has remained unpublished. The guidelines below come from the 7th edition of the Publication Manual of the American Psychological Association (2020a), pages 333 and 334. Please note that the association is not affiliated with this guide.

Alternatively, you can visit EasyBib.com for helpful citation tools to cite your thesis or dissertation .

Guide Overview

Citing an unpublished thesis or dissertation, citing a published dissertation or thesis from a database, citing a thesis or dissertation published online but not from a database, citing a thesis or dissertation: reference overview, what you need.

Since unpublished theses can usually only be sourced in print form from a university library, the correct citation structure includes the university name where the publisher element usually goes.

Author’s last name, F. M. (Year published). Title in sentence case [Unpublished degree type thesis or dissertation]. Name of institution.

Ames, J. H., & Doughty, L. H. (1911). The proposed plans for the Iowa State College athletic field including the design of a reinforced concrete grandstand and wall [Unpublished bachelor’s thesis]. Iowa State University.

In-text citation example:

• Parenthetical :  (Ames & Doughty, 1911)
• Narrative :  Ames & Doughty (1911)

If a thesis or dissertation has been published and is found on a database, then follow the structure below. It’s similar to the format for an unpublished dissertation/thesis, but with a few differences:

• The institution is presented in brackets after the title
• The archive or database name is included

Author’s last name, F. M. (Year published). Title in sentence case (Publication or Document No.) [Degree type thesis or dissertation, Name of institution]. Database name.

Examples 1:

Knight, K. A. (2011). Media epidemics: Viral structures in literature and new media (Accession No. 2013420395) [Doctoral dissertation, University of California, Santa Barbara]. ProQuest Dissertations Publishing.

Trotman, J.B. (2018). New insights into the biochemistry and cell biology of RNA recapping (Document No. osu1523896565730483) [Doctoral dissertation, Ohio State University]. OhioLINK Electronic Theses & Dissertations Center.

In the example given above, the dissertation is presented with a Document Number (Document No.). Sometimes called a database number or publication number, this is the identifier that is used by the database’s indexing system. If the database you are using provides you with such a number, then include it directly after the work’s title in parentheses.

If you are interested in learning more about how to handle works that were accessed via academic research databases, see Section 9.3 of the Publication Manual.

In-text citation examples :

• Parenthetical citation : (Trotman, 2018)
• Narrative citation : Trotman (2018)

Author’s last name, F. M. (Year Published). Title in sentence case [Degree type thesis or dissertation, Name of institution]. Name of archive or collection. URL

Kim, O. (2019). Soviet tableau: cinema and history under late socialism [Doctoral dissertation, University of Pittsburgh]. Institutional Repository at the University of Pittsburgh. https://d-scholarship.pitt.edu/37669/7/Olga%20Kim%20Final%20ETD.pdf

Stiles, T. W. (2001). Doing science: Teachers’ authentic experiences at the Lone Star Dinosaur Field Institute [Master’s thesis, Texas A&M University]. OAKTrust. https://hdl.handle.net/1969.1/ETD-TAMU-2001-THESIS-S745

It is important to note that not every thesis or dissertation published online will be associated with a specific archive or collection. If the work is published on a private website, provide only the URL as the source element.

In-text citation examples:

• Parenthetical citation : (Kim, 2019)
• Narrative citation : Kim (2019)
• Parenthetical citation : (Stiles, 2001)
• Narrative citation : Stiles (2001)

We hope that the information provided here will serve as an effective guide for your research. If you’re looking for even more citation info, visit EasyBib.com for a comprehensive collection of educational materials covering multiple source types.

If you’re citing a variety of different sources, consider taking the EasyBib citation generator for a spin. It can help you cite easily and offers citation forms for several different kinds of sources.

To start things off, let’s take a look at the different types of literature that are classified under Chapter 10.6 of the Publication Manual :

• Undergraduate thesis
• Master’s thesis
• Doctoral dissertation

You will need to know which type you are citing. You’ll also need to know if it is published or unpublished .

When you decide to cite a dissertation or thesis, you’ll need to look for the following information to use in your citation:

• Author’s last name, and first and middle initials
• Year published
• Title of thesis or dissertation
• If it is unpublished
• Publication or document number (if applicable; for published work)
• Degree type (bachelor’s, master’s, doctoral)
• Thesis or dissertation
• Name of institution awarding degree
• DOI (https://doi.org/xxxxx) or URL (if applicable)

Since theses and dissertations are directly linked to educational degrees, it is necessary to list the name of the associated institution; i.e., the college, university, or school that is awarding the associated degree.

To get an idea of the proper form, take a look at the examples below. There are three outlined scenarios:

• Unpublished thesis or dissertation
• Published thesis or dissertation from a database
• Thesis or dissertation published online but not from a database

Reference List: Common Reference List Examples

Article (with doi).

Alvarez, E., & Tippins, S. (2019). Socialization agents that Puerto Rican college students use to make financial decisions. Journal of Social Change , 11 (1), 75–85. https://doi.org/10.5590/JOSC.2019.11.1.07

Laplante, J. P., & Nolin, C. (2014). Consultas and socially responsible investing in Guatemala: A case study examining Maya perspectives on the Indigenous right to free, prior, and informed consent. Society & Natural Resources , 27 , 231–248. https://doi.org/10.1080/08941920.2013.861554

Use the DOI number for the source whenever one is available. DOI stands for "digital object identifier," a number specific to the article that can help others locate the source. In APA 7, format the DOI as a web address. Active hyperlinks for DOIs and URLs should be used for documents meant for screen reading. Present these hyperlinks in blue and underlined text (the default formatting in Microsoft Word), although plain black text is also acceptable. Be consistent in your formatting choice for DOIs and URLs throughout your reference list. Also see our Quick Answer FAQ, "Can I use the DOI format provided by library databases?"

Jerrentrup, A., Mueller, T., Glowalla, U., Herder, M., Henrichs, N., Neubauer, A., & Schaefer, J. R. (2018). Teaching medicine with the help of “Dr. House.” PLoS ONE , 13 (3), Article e0193972. https://doi.org/10.1371/journal.pone.0193972

For journal articles that are assigned article numbers rather than page ranges, include the article number in place of the page range.

For more on citing electronic resources, see  Electronic Sources References .

Article (Without DOI)

Found in a common academic research database or in print.

Casler , T. (2020). Improving the graduate nursing experience through support on a social media platform. MEDSURG Nursing , 29 (2), 83–87.

If an article does not have a DOI and you retrieved it from a common academic research database through the university library, there is no need to include any additional electronic retrieval information. The reference list entry looks like the entry for a print copy of the article. (This format differs from APA 6 guidelines that recommended including the URL of a journal's homepage when the DOI was not available.) Note that APA 7 has additional guidance on reference list entries for articles found only in specific databases or archives such as Cochrane Database of Systematic Reviews, UpToDate, ProQuest Dissertations and Theses Global, and university archives. See APA 7, Section 9.30 for more information.

Found on an Open Access Website

Eaton, T. V., & Akers, M. D. (2007). Whistleblowing and good governance. CPA Journal , 77 (6), 66–71. http://archives.cpajournal.com/2007/607/essentials/p58.htm

Provide the direct web address/URL to a journal article found on the open web, often on an open access journal's website. In APA 7, active hyperlinks for DOIs and URLs should be used for documents meant for screen reading. Present these hyperlinks in blue and underlined text (the default formatting in Microsoft Word), although plain black text is also acceptable. Be consistent in your formatting choice for DOIs and URLs throughout your reference list.

Weinstein, J. A. (2010).  Social change  (3rd ed.). Rowman & Littlefield.

If the book has an edition number, include it in parentheses after the title of the book. If the book does not list any edition information, do not include an edition number. The edition number is not italicized.

American Nurses Association. (2015). Nursing: Scope and standards of practice (3rd ed.).

If the author and publisher are the same, only include the author in its regular place and omit the publisher.

Lencioni, P. (2012). The advantage: Why organizational health trumps everything else in business . Jossey-Bass. https://amzn.to/343XPSJ

As a change from APA 6 to APA 7, it is no longer necessary to include the ebook format in the title. However, if you listened to an audiobook and the content differs from the text version (e.g., abridged content) or your discussion highlights elements of the audiobook (e.g., narrator's performance), then note that it is an audiobook in the title element in brackets. For ebooks and online audiobooks, also include the DOI number (if available) or nondatabase URL but leave out the electronic retrieval element if the ebook was found in a common academic research database, as with journal articles. APA 7 allows for the shortening of long DOIs and URLs, as shown in this example. See APA 7, Section 9.36 for more information.

Chapter in an Edited Book

Poe, M. (2017). Reframing race in teaching writing across the curriculum. In F. Condon & V. A. Young (Eds.), Performing antiracist pedagogy in rhetoric, writing, and communication (pp. 87–105). University Press of Colorado.

Include the page numbers of the chapter in parentheses after the book title.

Christensen, L. (2001). For my people: Celebrating community through poetry. In B. Bigelow, B. Harvey, S. Karp, & L. Miller (Eds.), Rethinking our classrooms: Teaching for equity and justice (Vol. 2, pp. 16–17). Rethinking Schools.

Also include the volume number or edition number in the parenthetical information after the book title when relevant.

Freud, S. (1961). The ego and the id. In J. Strachey (Ed.),  The standard edition of the complete psychological works of Sigmund Freud  (Vol. 19, pp. 3-66). Hogarth Press. (Original work published 1923)

When a text has been republished as part of an anthology collection, after the author’s name include the date of the version that was read. At the end of the entry, place the date of the original publication inside parenthesis along with the note “original work published.” For in-text citations of republished work, use both dates in the parenthetical citation, original date first with a slash separating the years, as in this example: Freud (1923/1961). For more information on reprinted or republished works, see APA 7, Sections 9.40-9.41.

Classroom Resources

Citing classroom resources.

If you need to cite content found in your online classroom, use the author (if there is one listed), the year of publication (if available), the title of the document, and the main URL of Walden classrooms. For example, you are citing study notes titled "Health Effects of Exposure to Forest Fires," but you do not know the author's name, your reference entry will look like this:

Health effects of exposure to forest fires [Lecture notes]. (2005). Walden University Canvas. https://waldenu.instructure.com

If you do know the author of the document, your reference will look like this:

Smith, A. (2005). Health effects of exposure to forest fires [PowerPoint slides]. Walden University Canvas. https://waldenu.instructure.com  

A few notes on citing course materials:

• [Lecture notes]
• [Course handout]
• [Study notes]
• It can be difficult to determine authorship of classroom documents. If an author is listed on the document, use that. If the resource is clearly a product of Walden (such as the course-based videos), use Walden University as the author. If you are unsure or if no author is indicated, place the title in the author spot, as above.
• If you cannot determine a date of publication, you can use n.d. (for "no date") in place of the year.

Note:  The web location for Walden course materials is not directly retrievable without a password, and therefore, following APA guidelines, use the main URL for the class sites: https://class.waldenu.edu.

Citing Tempo Classroom Resources

Clear author: 

Smith, A. (2005). Health effects of exposure to forest fires [PowerPoint slides]. Walden University Brightspace. https://mytempo.waldenu.edu

Unclear author:

Dictionary Entry

Merriam-Webster. (n.d.). Leadership. In Merriam-Webster.com dictionary . Retrieved May 28, 2020, from https://www.merriam-webster.com/dictionary/leadership

When constructing a reference for an entry in a dictionary or other reference work that has no byline (i.e., no named individual authors), use the name of the group—the institution, company, or organization—as author (e.g., Merriam Webster, American Psychological Association, etc.). The name of the entry goes in the title position, followed by "In" and the italicized name of the reference work (e.g., Merriam-Webster.com dictionary , APA dictionary of psychology ). In this instance, APA 7 recommends including a retrieval date as well for this online source since the contents of the page change over time. End the reference entry with the specific URL for the defined word.

Interactive Guide

OASIS. (n.d.). Embrace iterative research and writing [Interactive guide]. Walden University. https://academics.waldenu.edu/oasis/iterative-research-writing-web

Online Video/Webcast

Walden University. (2013).  An overview of learning  [Video]. Walden University Canvas.  https://waldenu.instructure.com  

Use this format for online videos such as Walden videos in classrooms. Most of our classroom videos are produced by Walden University, which will be listed as the author in your reference and citation. Note: Some examples of audiovisual materials in the APA manual show the word “Producer” in parentheses after the producer/author area. In consultation with the editors of the APA manual, we have determined that parenthetical is not necessary for the videos in our courses. The manual itself is unclear on the matter, however, so either approach should be accepted. Note that the speaker in the video does not appear in the reference list entry, but you may want to mention that person in your text. For instance, if you are viewing a video where Tobias Ball is the speaker, you might write the following: Tobias Ball stated that APA guidelines ensure a consistent presentation of information in student papers (Walden University, 2013). For more information on citing the speaker in a video, see our page on Common Citation Errors .

OASIS. (2020, April 15). One-way ANCOVA: Introduction [Video]. YouTube. https://youtu.be/_XnNDQ5CNW8

For videos from streaming sites, use the person or organization who uploaded the video in the author space to ensure retrievability, whether or not that person is the speaker in the video. A username can be provided in square brackets. As a change from APA 6 to APA 7, include the publisher after the title, and do not use "Retrieved from" before the URL. See APA 7, Section 10.12 for more information and examples.

Technical and research reports by governmental agencies and other research institutions usually follow a different publication process than scholarly, peer-reviewed journals. However, they present original research and are often useful for research papers. Sometimes, researchers refer to these types of reports as gray literature , and white papers are a type of this literature. See APA 7, Section 10.4 for more information.

Reference list entires for TED Talks follow the usual guidelines for multimedia content found online. There are two common places to find TED talks online, with slightly different reference list entry formats for each.

TED Talk on the TED website

If you find the TED Talk on the TED website, follow the format for an online video on an organizational website:

Owusu-Kesse, K. (2020, June). 5 needs that any COVID-19 response should meet [Video]. TED Conferences. https://www.ted.com/talks/kwame_owusu_kesse_5_needs_that_any_covid_19_response_should_meet

The speaker is the author in the reference list entry if the video is posted on the TED website. For citations, use the speaker's surname.

TED Talk on YouTube

If you find the TED Talk on YouTube or another streaming video website, follow the usual format for streaming video sites:

TED. (2021, February 5). The shadow pandemic of domestic violence during COVID-19 | Kemi DaSilvalbru [Video]. YouTube. https://www.youtube.com/watch?v=PGdID_ICFII

TED is the author in the reference list entry if the video is posted on YouTube since it is the channel on which the video is posted. For citations, use TED as the author.

Walden University Course Catalog

To include the Walden course catalog in your reference list, use this format:

Walden University. (2020). 2019-2020 Walden University catalog . https://catalog.waldenu.edu/index.php

If you cite from a specific portion of the catalog in your paper, indicate the appropriate section and paragraph number in your text:

...which reflects the commitment to social change expressed in Walden University's mission statement (Walden University, 2020, Vision, Mission, and Goals section, para. 2).

And in the reference list:

Walden University. (2020). Vision, mission, and goals. In 2019-2020 Walden University catalog. https://catalog.waldenu.edu/content.php?catoid=172&navoid=59420&hl=vision&returnto=search

Vartan, S. (2018, January 30). Why vacations matter for your health . CNN. https://www.cnn.com/travel/article/why-vacations-matter/index.html

For webpages on the open web, include the author, date, webpage title, organization/site name, and URL. (There is a slight variation for online versions of print newspapers or magazines. For those sources, follow the models in the previous sections of this page.)

American Federation of Teachers. (n.d.). Community schools . http://www.aft.org/issues/schoolreform/commschools/index.cfm

If there is no specified author, then use the organization’s name as the author. In such a case, there is no need to repeat the organization's name after the title.

In APA 7, active hyperlinks for DOIs and URLs should be used for documents meant for screen reading. Present these hyperlinks in blue and underlined text (the default formatting in Microsoft Word), although plain black text is also acceptable. Be consistent in your formatting choice for DOIs and URLs throughout your reference list.

Thesis and dissertation can mean different things, depending on which institution the work is from.  For study purposes and for your APA reference you need to know the level of the work.

• Always check the title page, or subsequent pages, to determine exactly what the work is
• Use the information there for your APA reference

At Auckland University of Technology (and other NZ universities)

Thesis is either for a doctoral or a master's degree.

Dissertation is either for a master's or a bachelor's degree with honours.

Exegesis is the written component of a practice-based thesis where the major output is a creative work;  e.g. a film, artwork, novel.

In some other parts of the world such as North America, a dissertation may be for a doctoral degree and a thesis for a master's degree.  

See Section 7.05  in the Publication Manual of the American Psychological Association, 6th edition .

How do you cite a  youtube  video? Books with 3 authors? Articles from an online database?  Check out this  Reference Examples PDF

Here are some of the guidelines for your reference page.  Your references should include ALL resources that your cited in your thesis.  In other words, if you used an in-text citation, I should be able to find the source in your list of references.

• Your works cited page should be titled References and begin on its own page.
• Need more information on where your reference is located in your thesis?
• After the first line of each reference all others should be indented a half inch, this is referred to as a "hanging indentation" and you can format it in Microsoft Word if you highlight the citation right click, and choose paragraph.
• List your citations in alphabetical order.
• List page numbers as ranges, first-last (17-23) rather than refer to all pages read.
• For online resources include URLs / DOIs.  You do not need to say "retrieved from" or include the date the information was accessed.
• Capitalize each word in the titles of your sources except for articles such as the, an, with, etc. Only capitalize those articles that are at the beginning of a title such as  The Wizard of OZ.
• Use italics for titles of works (e.g. books and films).
• List author names Last, First Initial. Middle Initial (should there be one), such as Campbell, L. G.
• If you cite more than one work by an author, list them alphabetically by title.
• Cite a work with no known author by its title.
• Items that are not text (for example YouTube videos and images) need a [media type] after the title. For instance a reference for a photo would have [photograph] after the title.

Reference Examples

More than 100 reference examples and their corresponding in-text citations are presented in the seventh edition Publication Manual . Examples of the most common works that writers cite are provided on this page; additional examples are available in the Publication Manual .

To find the reference example you need, first select a category (e.g., periodicals) and then choose the appropriate type of work (e.g., journal article ) and follow the relevant example.

When selecting a category, use the webpages and websites category only when a work does not fit better within another category. For example, a report from a government website would use the reports category, whereas a page on a government website that is not a report or other work would use the webpages and websites category.

Also note that print and electronic references are largely the same. For example, to cite both print books and ebooks, use the books and reference works category and then choose the appropriate type of work (i.e., book ) and follow the relevant example (e.g., whole authored book ).

Examples on these pages illustrate the details of reference formats. We make every attempt to show examples that are in keeping with APA Style’s guiding principles of inclusivity and bias-free language. These examples are presented out of context only to demonstrate formatting issues (e.g., which elements to italicize, where punctuation is needed, placement of parentheses). References, including these examples, are not inherently endorsements for the ideas or content of the works themselves. An author may cite a work to support a statement or an idea, to critique that work, or for many other reasons. For more examples, see our sample papers .

Reference examples are covered in the seventh edition APA Style manuals in the Publication Manual Chapter 10 and the Concise Guide Chapter 10

What is a thesis?

What is a dissertation, getting started, staying on track.

A thesis is a long-term project that you work on over the course of a semester or a year. Theses have a very wide variety of styles and content, so we encourage you to look at prior examples and work closely with faculty to develop yours. 

Before you begin, make sure that you are familiar with the dissertation genre—what it is for and what it looks like.

Generally speaking, a dissertation’s purpose is to prove that you have the expertise necessary to fulfill your doctoral-degree requirements by showing depth of knowledge and independent thinking.

The form of a dissertation may vary by discipline. Be sure to follow the specific guidelines of your department.

• PhD This site directs candidates to the GSAS website about dissertations , with links to checklists,  planning, formatting, acknowledgments, submission, and publishing options. There is also a link to guidelines for the prospectus . Consult with your committee chair about specific requirements and standards for your dissertation.
• DDES This document covers planning, patent filing, submission guidelines, publishing options, formatting guidelines, sample pages, citation guidelines, and a list of common errors to avoid. There is also a link to guidelines for the prospectus .
• Scholarly Pursuits (GSAS) This searchable booklet from Harvard GSAS is a comprehensive guide to writing dissertations, dissertation-fellowship applications, academic journal articles, and academic job documents.

Finding an original topic can be a daunting and overwhelming task. These key concepts can help you focus and save time.

Finding a topic for your thesis or dissertation should start with a research question that excites or at least interests you. A rigorous, engaging, and original project will require continuous curiosity about your topic, about your own thoughts on the topic, and about what other scholars have said on your topic. Avoid getting boxed in by thinking you know what you want to say from the beginning; let your research and your writing evolve as you explore and fine-tune your focus through constant questioning and exploration.

Get a sense of the broader picture before you narrow your focus and attempt to frame an argument. Read, skim, and otherwise familiarize yourself with what other scholars have done in areas related to your proposed topic. Briefly explore topics tangentially related to yours to broaden your perspective and increase your chance of finding a unique angle to pursue.

Critical Reading

Critical reading is the opposite of passive reading. Instead of merely reading for information to absorb, critical reading also involves careful, sustained thinking about what you are reading. This process may include analyzing the author’s motives and assumptions, asking what might be left out of the discussion, considering what you agree with or disagree with in the author’s statements and why you agree or disagree, and exploring connections or contradictions between scholarly arguments. Here is a resource to help hone your critical-reading skills:

http://writing.umn.edu/sws/assets/pdf/quicktips/criticalread.pdf

Conversation

Your thesis or dissertation will incorporate some ideas from other scholars whose work you researched. By reading critically and following your curiosity, you will develop your own ideas and claims, and these contributions are the core of your project. You will also acknowledge the work of scholars who came before you, and you must accurately and fairly attribute this work and define your place within the larger discussion. Make sure that you know how to quote, summarize, paraphrase ,  integrate , and cite secondary sources to avoid plagiarism and to show the depth and breadth of your knowledge.

A thesis is a long-term, large project that involves both research and writing; it is easy to lose focus, motivation, and momentum. Here are suggestions for achieving the result you want in the time you have.

The dissertation is probably the largest project you have undertaken, and a lot of the work is self-directed. The project can feel daunting or even overwhelming unless you break it down into manageable pieces and create a timeline for completing each smaller task. Be realistic but also challenge yourself, and be forgiving of yourself if you miss a self-imposed deadline here and there.

Your program will also have specific deadlines for different requirements, including establishing a committee, submitting a prospectus, completing the dissertation, defending the dissertation, and submitting your work. Consult your department’s website for these dates and incorporate them into the timeline for your work.

Accountability

Sometimes self-imposed deadlines do not feel urgent unless there is accountability to someone beyond yourself. To increase your motivation to complete tasks on schedule, set dates with your committee chair to submit pre-determined pieces of a chapter. You can also arrange with a fellow doctoral student to check on each other’s progress. Research and writing can be lonely, so it is also nice to share that journey with someone and support each other through the process.

Common Pitfalls

The most common challenges for students writing a dissertation are writer’s block, information-overload, and the compulsion to keep researching forever.

There are many strategies for avoiding writer’s block, such as freewriting, outlining, taking a walk, starting in the middle, and creating an ideal work environment for your particular learning style. Pay attention to what helps you and try different things until you find what works.

Efficient researching techniques are essential to avoiding information-overload. Here are a couple of resources about strategies for finding sources and quickly obtaining essential information from them.

https://owl.purdue.edu/owl/subject_specific_writing/writing_in_literature/writing_in_literature_detailed_discussion/reading_criticism.html

https://students.dartmouth.edu/academic-skills/learning-resources/learning-strategies/reading-techniques

Finally, remember that there is always more to learn and your dissertation cannot incorporate everything. Follow your curiosity but also set limits on the scope of your work. It helps to create a folder entitled “future projects” for topics and sources that interest you but that do not fit neatly into the dissertation. Also remember that future scholars will build off of your work, so leave something for them to do.

Browsing through theses and dissertations of the past can help to get a sense of your options and gain inspiration but be careful to use current guidelines and refer to your committee instead of relying on these examples for form or formatting.

Important Note: Because the 7 th edition of the APA Publication Manual heavily emphasizes digital and electronic sources, it does not contain explicit instructions for certain less-common print sources that earlier editions covered. For this reason, some of the examples below have been adapted from the instructions for sources with similar attributes (e.g., the conference proceedings example is derived from the instructions the 7 th edition manual gives for citing edited collections). Every example below that has been adapted in this way is accompanied by a note explaining how it was adapted.

Entry in a Dictionary, Thesaurus, or Encyclopedia with a Group Author

The 7 th edition of the APA manual does not provide specific guidance on how to cite physical reference works such as dictionaries, thesauruses, or encyclopedias. Therefore, this citation, as well as the one for an individual author of an entry in a reference work, is modeled on that of a chapter in an edited book or anthology, both which are similar in format to reference works.

How do I find references and how do I know that they are valid?

I took a pause from school during personal problems and started it again half-year ago. Now that I've finished almost all of it, the last thing I have left is to finish my thesis-work.

My professor stated that for my work I need to look up references that validates and proves for what I've stated in my report (Which is logical), but my problem is what the title is given out.

How do I know that the reference is valid?

• Where is the best place to find references? (For my case it's about software-development )
• literature-search
• cross-referencing

• Might be related to academia.stackexchange.com/questions/83449/… –  FuzzyLeapfrog Commented Feb 13, 2017 at 11:44
• Try to search on google scholar (scholar.google.com). It also has an export citation feature. –  Lot Commented Feb 13, 2017 at 11:46
• I used it yesterday. That is why I'm asking this question today. –  Bojje Commented Feb 13, 2017 at 11:54
• @Lot what do you mean with export citation feature? –  Bojje Commented Feb 13, 2017 at 12:03
• 3 @Bojje do you have a library at your institution? Librarian are great people that are paid to help you with that. In some University, they even have short classes about looking for reference or tutorials... –  Emilie Commented Feb 13, 2017 at 13:56

In general, these questions indicate a quite fundamental gap of knowledge in how science works. It is a pity that your coursework has not prepared you better for your thesis.

There is no magic wand that tells you that. You will need to carefully read the papers, consider their limitations and threats to validity, and decide for yourself whether the paper is useful as a source to support your argument. That being said, as a first approximation you can look at the venue that the paper has been published in (is the journal or the conference very good?), and how often the paper has been cited by others (you can see that in Google Scholar). However, again, keep in mind that all of this is just supporting data - ultimately you need to decide yourself whether a given piece of research is valid and useful.

Where is the best place to find references? (For my case it's about software-development)

There are three common strategies for finding literature:

• Searching a digital library (in your case e.g., IEEEXplorer or the ACM DL ), searching through DBLP , or using Google Scholar . In all of these cases, you can investigate a lot of different journals and conference proceedings at the same time, but you need to be aware of the right keywords to search for.
• Browsing journal back issues or conference proceedings. That is, after you have identified important journals and conferences in your field (for you ICSE might be a starting point), go over previous iterations and look over all paper titles and abstracts. The most convenient way in computer science to do this is via the aforementioned DBLP.
• Once you have a few good papers as starting point, start following the chain of references. Look at both, the papers that your papers are citing, but also which papers cite the papers you already found (Google Scholar has a feature for this).

You can find a summary of this also in a presentation I recently did as part of my own seminar.

How do I know that the reference is valid? For thesis work, valid references are generally ones published by reputable journals and have been peer-reviewed. Generally, books and articles published on educational or governmental websites are safe.

Where is the best place to find references? (For my case it's about software-development) As @Emilie mentioned in the comments, your university library would be a great place to start. If not, then a public library. You could ask your professor for recommendations as well.

How to Cite Sources | Citation Generator & Quick Guide

Citing your sources is essential in  academic writing . Whenever you quote or paraphrase a source (such as a book, article, or webpage), you have to include a  citation crediting the original author.

Failing to properly cite your sources counts as plagiarism , since you’re presenting someone else’s ideas as if they were your own.

The most commonly used citation styles are APA and MLA. The free Scribbr Citation Generator is the quickest way to cite sources in these styles. Simply enter the URL, DOI, or title, and we’ll generate an accurate, correctly formatted citation.

Other useful citation tools

Citation examples and full guides, frequently asked questions about citing sources.

Citations are required in all types of academic texts. They are needed for several reasons:

• To avoid plagiarism by indicating when you’re taking information from another source
• To give proper credit to the author of that source
• To allow the reader to consult your sources for themselves

A citation is needed whenever you integrate a source into your writing. This usually means quoting or paraphrasing:

• To quote a source , copy a short piece of text word for word and put it inside quotation marks .
• To paraphrase a source , put the text into your own words. It’s important that the paraphrase is not too close to the original wording. You can use the paraphrasing tool if you don’t want to do this manually.

Citations are needed whether you quote or paraphrase, and whatever type of source you use. As well as citing scholarly sources like books and journal articles, don’t forget to include citations for any other sources you use for ideas, examples, or evidence. That includes websites, YouTube videos , and lectures .

Scribbr Citation Checker New

The AI-powered Citation Checker helps you avoid common mistakes such as:

• Missing commas and periods
• Incorrect usage of “et al.”
• Ampersands (&) in narrative citations
• Missing reference entries

Usually, your institution (or the journal you’re submitting to) will require you to follow a specific citation style, so check your guidelines or ask your instructor.

In some cases, you may have to choose a citation style for yourself. Make sure to pick one style and use it consistently:

• APA Style is widely used in the social sciences and beyond.
• MLA style is common in the humanities.
• Chicago notes and bibliography , common in the humanities
• Chicago author-date , used in the (social) sciences
• There are many other citation styles for different disciplines.

If in doubt, check with your instructor or read other papers from your field of study to see what style they follow.

In most styles, your citations consist of:

• Brief in-text citations at the relevant points in the text
• A reference list or bibliography containing full information on all the sources you’ve cited

In-text citations most commonly take the form of parenthetical citations featuring the last name of the source’s author and its year of publication (aka author-date citations).

An alternative to this type of in-text citation is the system used in numerical citation styles , where a number is inserted into the text, corresponding to an entry in a numbered reference list.

There are also note citation styles , where you place your citations in either footnotes or endnotes . Since they’re not embedded in the text itself, these citations can provide more detail and sometimes aren’t accompanied by a full reference list or bibliography.

A reference list (aka “Bibliography” or “Works Cited,” depending on the style) is where you provide full information on each of the sources you’ve cited in the text. It appears at the end of your paper, usually with a hanging indent applied to each entry.

The information included in reference entries is broadly similar, whatever citation style you’re using. For each source, you’ll typically include the:

• Author name
• Publication date
• Container (e.g., the book an essay was published in, the journal an article appeared in)
• Location (e.g., a URL or DOI , or sometimes a physical location)

The exact information included varies depending on the source type and the citation style. The order in which the information appears, and how you format it (e.g., capitalization, use of italics) also varies.

Most commonly, the entries in your reference list are alphabetized by author name. This allows the reader to easily find the relevant entry based on the author name in your in-text citation.

In numerical citation styles, the entries in your reference list are numbered, usually based on the order in which you cite them. The reader finds the right entry based on the number that appears in the text.

Citation Editing

Plagiarism means passing off someone else’s words or ideas as your own. It’s a serious offense in academia. Universities use plagiarism checking software to scan your paper and identify any similarities to other texts.

When you’re dealing with a lot of sources, it’s easy to make mistakes that could constitute accidental plagiarism. For example, you might forget to add a citation after a quote, or paraphrase a source in a way that’s too close to the original text.

Using a plagiarism checker yourself before you submit your work can help you spot these mistakes before they get you in trouble. Based on the results, you can add any missing citations and rephrase your text where necessary.

At college level, you must properly cite your sources in all essays , research papers , and other academic texts (except exams and in-class exercises).

Add a citation whenever you quote , paraphrase , or summarize information or ideas from a source. You should also give full source details in a bibliography or reference list at the end of your text.

The exact format of your citations depends on which citation style you are instructed to use. The most common styles are APA , MLA , and Chicago .

The abbreviation “ et al. ” (Latin for “and others”) is used to shorten citations of sources with multiple authors.

“Et al.” is used in APA in-text citations of sources with 3+ authors, e.g. (Smith et al., 2019). It is not used in APA reference entries .

Use “et al.” for 3+ authors in MLA in-text citations and Works Cited entries.

Use “et al.” for 4+ authors in a Chicago in-text citation , and for 10+ authors in a Chicago bibliography entry.

The Scribbr Citation Generator is developed using the open-source Citation Style Language (CSL) project and Frank Bennett’s citeproc-js . It’s the same technology used by dozens of other popular citation tools, including Mendeley and Zotero.

You can find all the citation styles and locales used in the Scribbr Citation Generator in our publicly accessible repository on Github .

APA format is widely used by professionals, researchers, and students in the social and behavioral sciences, including fields like education, psychology, and business.

Be sure to check the guidelines of your university or the journal you want to be published in to double-check which style you should be using.

MLA Style  is the second most used citation style (after APA ). It is mainly used by students and researchers in humanities fields such as literature, languages, and philosophy.
