The Basic Rule

Cite your own previous work the same way you'd cite any other author. Use your name, not first person.

Correct:

Previous research found similar patterns (Martinez, 2022).

Incorrect:

In my previous research, I found similar patterns (Martinez, 2022).

This might feel awkward, but it's standard academic practice. It keeps your writing consistent and professional.

Why Self-Citation Matters

Self-citation is legitimate and often necessary. It shows how your work builds on your previous research, avoids self-plagiarism by properly attributing your earlier writing, provides readers with relevant background, and establishes the trajectory of your research program.

The issue isn't self-citation itself—it's inappropriate self-citation.

When Self-Citation Is Appropriate

Cite your own work when it directly supports or informs the current study, when you're building on methods or frameworks you developed, when readers need your previous work to understand this one, and when it's the most relevant source (not just a relevant source).

When to Avoid Self-Citation

Don't cite yourself when the citation is tangential (just padding your numbers), when better or more authoritative sources exist, when it's excessive relative to the topic's scope, or when you're trying to manipulate citation metrics.

Reviewers and editors notice gratuitous self-citation. It can undermine your credibility.

Citing Published Work

For your own published papers, use standard citation format:

APA:

Martinez, J. R. (2022). Title of your article. Journal Name, 12(3), 45-67. https://doi.org/xxxxx

MLA:

Martinez, J. R. "Title of Your Article." Journal Name, vol. 12, no. 3, 2022, pp. 45-67.

Nothing special required—treat it like any other publication.

Citing Your Thesis or Dissertation

Theses and dissertations have their own format:

APA:

Martinez, J. R. (2021). Title of dissertation [Doctoral dissertation, University Name]. Database Name. https://doi.org/xxxxx

MLA:

Martinez, J. R. Title of Dissertation. 2021. University Name, PhD dissertation.

Citing Unpublished Work

For manuscripts in preparation, submitted, or under review:

APA:

Martinez, J. R. (2024). Title of manuscript. Unpublished manuscript.

Or if submitted:

Martinez, J. R. (2024). Title of manuscript. Manuscript submitted for publication.

Be cautious about citing work that isn't yet peer-reviewed or accepted. Readers can't verify or access it.

Citing Your Own Data or Materials

If you're referencing raw data, instruments, or materials from your previous research:

The survey instrument was developed and validated in Martinez (2022).

For datasets, some repositories assign DOIs—cite those directly.

Blind Peer Review Considerations

Many journals use blind review, where reviewers shouldn't know who wrote the paper. Self-citations can reveal your identity.

Check journal guidelines. Some ask you to anonymize self-citations in the submitted version:

Previous research found similar patterns (Author, Year). [BLINDED FOR REVIEW]

Others say to cite normally—they'll handle it. Follow the specific journal's instructions.

The Self-Plagiarism Question

Self-citation and self-plagiarism are different issues.

Self-citation = attributing your previous ideas/findings to yourself. This is proper.

Self-plagiarism = reusing your previous text without acknowledgment. This is problematic.

If you're reusing substantial text from your previous work, you need to either quote yourself (with citation), paraphrase (with citation), or get permission if copyright was transferred to a publisher.

How Much Self-Citation Is Too Much?

There's no fixed rule, but consider proportion. If 30% of your citations are self-citations, that might raise eyebrows—unless you're the leading researcher in a narrow field.

A good test: would a neutral observer agree that each self-citation is the most relevant source? If not, find alternative citations or cut.
