Dissertation Reference List: How to Format It Correctly

The reference list is the part of a dissertation that nobody enjoys writing and every examiner checks. It shows whether your sources are real, relevant, and credited properly, and it is one of the easiest places to lose marks through carelessness. Missing entries, inconsistent punctuation, and citations that do not match the list all signal a rushed final stage, however good the chapters are.

This guide explains what a reference list must contain, how the three most common styles format the most common source types, and a checking routine you can run in an afternoon.

Reference List or Bibliography?

The two terms are often used as if they meant the same thing, but they do not.

• A reference list includes only the sources you cited in the text.
• A bibliography may also include sources you read but did not cite.

Most dissertations ask for a reference list. Some departments want a bibliography as well, or instead. Check your handbook before you start, because it changes what you include.

Rules That Apply in Every Style

Whatever style you use, a few rules are constant:

1. Every in-text citation must appear in the list, and every entry in the list must be cited in the text.
2. Entries are in alphabetical order by the first author's surname (APA, Harvard, MLA), unless your department uses a numbered style.
3. Use one style consistently from the first page to the last.
4. Use a hanging indent, where the first line is flush left and later lines are indented.
5. Include enough detail for a reader to find the source: author, year, title, and publication details.

Your department's guide always overrides general advice. If it differs from what you read here, follow your department.

Formatting by Style: Common Source Types

The examples below use placeholder names to show the pattern. Details such as capitalization and punctuation vary slightly between editions and universities, so confirm them against your own style guide.

APA (7th edition)

Journal article: Smith, J. A., & Lee, R. (2021). Sleep and academic performance in first-year students. Journal of Student Health, 12(3), 45-62. https://doi.org/10.0000/example

Book: Jones, M. (2019). Research methods in education (2nd ed.). Academic Press.

Webpage: World Health Organization. (2022, March 4). Mental health in the workplace. https://www.who.int/example

APA uses the author's initials, puts the year in parentheses after the author, and italicizes the journal name and volume. For the journal title, use title case; for the article title, capitalize only the first word and proper nouns.

Harvard

Journal article: Smith, J.A. and Lee, R. (2021) 'Sleep and academic performance in first-year students', Journal of Student Health, 12(3), pp. 45-62.

Book: Jones, M. (2019) Research methods in education. 2nd edn. London: Academic Press.

Webpage: World Health Organization (2022) Mental health in the workplace. Available at: https://www.who.int/example (Accessed: 12 May 2024).

Harvard has no single official version. Universities publish their own guides, so the placement of commas, the use of "edn.", and the access-date format may differ. Always follow your institution's version.

MLA (9th edition)

Journal article: Smith, Jane A., and Robert Lee. "Sleep and Academic Performance in First-Year Students." Journal of Student Health, vol. 12, no. 3, 2021, pp. 45-62.

Book: Jones, Mark. Research Methods in Education. 2nd ed., Academic Press, 2019.

Webpage: World Health Organization. "Mental Health in the Workplace." World Health Organization, 4 Mar. 2022, www.who.int/example.

MLA gives full author names, uses title case for all titles, and lists the page range at the end. The list is called "Works Cited."

Handling Awkward Sources

Some sources do not fit the standard patterns. Common examples:

• Secondary citations. If you read about a study in another author's book, cite the book you actually read, not the original. Most styles have a specific "cited in" format.
• No author. Use the organization as the author, or begin with the title if neither exists.
• No date. Use "n.d." in APA and Harvard.
• Interviews you conducted. Many styles do not list personal interviews in the reference list, because readers cannot retrieve them. Describe them in the text and in your methodology instead, and check your department's rule.
• Legislation, cases, and reports. These often have their own formats, especially in law. Check the style guide your department uses.

Use a Reference Manager, But Check Its Output

Tools such as Zotero, Mendeley, and EndNote save time and keep citations consistent. They are worth setting up on the first day of your project. But they are only as good as the data in them. Common problems include:

• Capitalization that does not follow your style.
• Missing page numbers or DOIs.
• Organizations listed as if they were people.
• Duplicate entries for the same source.

Treat the manager as a first draft of the list, then review every entry by hand.

A Checking Routine for the Final Week

1. Match citations to the list. Go through the text and tick each citation against the list. Then go through the list and confirm each entry is cited.
2. Check the details. Confirm author names, years, titles, volumes, and pages against the source itself.
3. Check consistency. Look at punctuation, italics, capitalization, and the format of DOIs and URLs.
4. Check ordering. Make sure the list is alphabetical and the hanging indent is applied throughout.
5. Check for dead links. Open each URL and replace any that no longer work.
6. Read it once as an examiner would. Does anything look different from the rest?

Common Mistakes That Cost Marks

• Citing sources in the text that are missing from the list.
• Listing sources that the text never cites.
• Mixing styles, such as APA journal formats with Harvard book formats.
• Copying entries from other documents without checking them.
• Citing a source you have not read.
• Forgetting the hanging indent or the alphabetical order.

If you want a second reader to catch what you stopped seeing after the fiftieth entry, our citation and reference formatting service is designed for exactly this stage. It checks consistency and format against your style guide, and it leaves your sources and arguments as you wrote them.

Summary

A strong reference list is complete, consistent, and accurate. Match every citation to an entry, use your department's style guide, check what your reference manager produces, and run a final routine before you submit.
