Citing a dissertation: university, year, examples

Published or not: how to cite a dissertation

A dissertation is the written work by which someone earns a doctorate, usually a substantial piece of independent research. How you cite it depends on whether it was published as a book or exists only as a university thesis. This guide explains the difference, which details belong in the reference, from the university to the year, and what the examples look like in the common citation styles.

What makes a dissertation a source

A dissertation, also called a doctoral thesis, is an academic qualification paper and can be a citable source. Its methodological and substantive quality still has to be assessed case by case: the status as a dissertation alone is not proof of quality. It can contain independent research findings that matter for your own argument.

Whether the type of work and the degree-awarding university appear in the reference is determined by the citation style you use and by the actual route of publication. For the original university thesis these details may be required; for a revised book edition, follow the rules for books. How to find peer-reviewed work in general is explained in a guide on systematic literature searching.

Published or unpublished: the key criterion

Whether you cite a dissertation by the book pattern or by the university thesis pattern depends on the actual route of publication and the citation style you use. An edition published by a publisher is normally cited by the rules for books; an electronic thesis published in an institutional repository follows the rules of the style concerned.

A dissertation can exist as a book, as an electronic thesis in an institutional repository or as an unpublished university thesis. Which details are required and in which order they appear depends on the chosen citation style, the route of publication and the details of the version in front of you. If in doubt, a look at the library catalogue and at the version you have helps you to determine the route of publication.

Citing a published dissertation

If the work appears with a publisher, follow the rules of your citation style for books. A note that the work was a doctoral thesis is only required if the citation style or a university rule asks for it. The following examples show a published book edition.

Fictional APA 7 example for a published book edition: Neumann, L. (2019). Digital self-regulation in higher education. Example Press.

Possible Harvard author-date entry for a published book edition: Neumann, L. (2019): Digital self-regulation in higher education. Bielefeld: Example Press.

You will find details on punctuation and bracket logic in the APA author-date system in the APA 7 guide.

Citing a dissertation: unpublished works and repository publications

If the work is only available as an unpublished university thesis, the academic context may be needed for the source reference. Depending on the citation style, you name the type of work and the university.

Fictional APA 7 example: Neumann, L. (2019). Digital self-regulation in higher education [Unpublished doctoral dissertation]. University of Hamburg.

If the dissertation is available as a published electronic thesis in a repository, give a URL, a DOI, a URN or another persistent link, where one exists. Add an access date if your citation style or your university's rules ask for it. Make sure that the reference leads unambiguously to the right version; the guide on giving references correctly has further hints.

Giving the university, year and type of work

Three details are particularly error-prone when citing:

University: the degree-awarding university, not the author's current employer or place of residence.
Year: the year of acceptance or of publication; for publisher editions the two can differ.
Type of work: for original university theses the label as a dissertation (in German sources often "Diss.") may be required; for revised publisher editions it depends on the citation style you use.

If the name of the university is missing, an unpublished doctoral thesis is hard to find and therefore hard to verify.

Typical mistakes and exceptions

When citing this type of source, bear the following in mind:

Published book versions follow the chosen style when it comes to the doctorate note and dissertation status.
Cumulative dissertations are cited either as a complete work or as a single contribution, depending on what you refer to.
For PDFs from repositories, use a DOI, a URN or a stable URL; give an access date only if the chosen citation style or the university's rules require it.

The front matter often contains details on the year, the university and the type of work. An explicit statement on acceptance can document the year of acceptance. The date of the defence or oral examination is not the same as the year of acceptance, even if the book edition appears later.

Also learn to cite other sources such as monographs and grey literature correctly. Our guide on citing sources correctly gives further hints.

FAQs on citing doctoral theses

How do I cite a dissertation correctly?

Whether the note "dissertation" and the university have to be named depends on the citation style you use and the actual route of publication. For original university theses, follow the requirements for this type of source; a revised book edition is cited by the rules for books. For online sources, give the URL, DOI or another persistent identifier, where one exists.

What is the difference between published and unpublished when citing a dissertation?

For published book editions, the chosen citation style determines whether and how the addition "dissertation" and the university appear. For unpublished university theses, the type of work and the university follow the rules of the style you use.

Which university do I give for a dissertation?

If your citation style asks for the university for a university thesis, name the degree-awarding university, not the author's later place of residence or employer. This detail is often found on the title page or in the bibliographic details. Do not confuse it with the publisher's place of publication, which is given separately for printed editions.

Is a dissertation a citable source?

Yes. Dissertations can be citable academic sources. Their methodological and substantive quality still has to be assessed case by case. For niche topics a doctoral thesis can be a detailed treatment and support your research.

How do I cite a dissertation from an online repository?

For a dissertation from an online repository, the reference follows the citation style you use and the details of the version in front of you. Give the URL, DOI, URN or another persistent identifier, where one exists; add an access date only if your citation style or your university's rules ask for it.
