Yes, you can cite yourself. It might feel strange, like talking to yourself in a crowded room, but in academic writing, it’s sometimes necessary. This guide explains how to cite yourself correctly, so you can avoid accidental plagiarism and give proper credit to your own previous ideas. You wrote it, you get the credit. Simple.
TLDR: Always check with your professor before you reuse any part of a previous paper. If you get the okay, you must cite yourself just like any other source. This means creating a full reference entry and using in-text citations for any direct quotes or paraphrased ideas from your past work. Failing to do so is self-plagiarism.
Why You Need to Cite Your Own Work
So, why all the fuss? You wrote the original words, so you can’t steal from yourself, right? In academic writing, the core principle is transparency. Your reader needs to know where your ideas originated. When you present old work as brand new, you’re breaking that trust. It’s a matter of intellectual honesty, a silent pact between writer and reader. Each assignment is typically expected to be a fresh piece of work, created for that specific course. Submitting a paper you’ve already gotten credit for is often against university policy. But what if a previous essay you’ve written contains the perfect foundation for your current research? That’s when you need to cite it.
Quick Tip: Before you even think about reusing a paper, email your instructor. A simple question like, “I did a related research paper last semester; may I use it as a source for this assignment?” can save you a world of trouble.
The biggest danger is self-plagiarism. This is when you reuse significant portions of your previous work without acknowledgment. It misleads your audience into thinking the content is entirely new. Most university honor codes treat self-plagiarism as seriously as regular plagiarism, and the consequences can be severe. I remember the cold dread of realizing I’d accidentally used a whole paragraph from a high school paper in a university assignment. I had to confess to my professor and resubmit. It was a lesson learned the hard way. Don’t let it happen to you. You must cite yourself to maintain your academic integrity.
Self-plagiarism isn’t limited to copying a whole paper. It also covers salami-slicing, sometimes known as breaking one study into several smaller papers to inflate your publication count, and duplicate submission, turning in the same assignment for credit in two different classes without permission. Neither practice is a copyright violation, since you own the words, but both are treated as academic dishonesty because they misrepresent how much original work you actually produced for the topic at hand. Whichever form it takes, if you reuse material from a past project, credit your previous paper the same way you would credit any outside work. The Purdue OWL plagiarism overview covers these categories in more depth.
Published vs. Unpublished Work
The way you cite yourself depends on whether your previous work was formally published or if it was an unpublished class paper. Most of the time for a student, you’ll be dealing with unpublished papers.
If your work is unpublished (like a class essay or assignment), you treat it as such in the citation. The goal is to give the reader enough information to understand the source, even if they can’t access it. You would simply note it as an “Unpublished manuscript” or “Unpublished paper.”
If your work has been published—maybe in a student journal, a blog, or as part of a conference proceeding—you would cite it just as you would cite anyone else’s published article or publication. You are the author, so your name goes first.
Here’s exactly how to cite yourself for the most common style guides when your paper is unpublished:
| Citation Style | Reference List Example | In-Text Citation Example |
|---|---|---|
| MLA 9 | Doe, Jane. “The Psychology of Procrastination.” 2023. English 101, University of Example, Unpublished essay. | (Doe, “Psychology” 7). |
| APA 7 | Doe, J. (2023). The psychology of procrastination [Unpublished manuscript]. Department of Psychology, University of Example. | (Doe, 2023, p. 7). |
| Chicago 17 | Doe, Jane. “The Psychology of Procrastination.” Unpublished paper, University of Example, 2023. | (Doe 2023, 7). |
Pro Tip: Tools can make this easier. A free citation generator can help you format these correctly, but always double-check its output against the official style guide rules for unpublished work.
What About Citing Other Forms of Your Own Work?
What if the work you want to refer to isn’t a formal paper? This is a far-flung possibility, but a real one. Maybe you kept a detailed research journal for a science project, or you translated a text for a language course. Yes, you should acknowledge this too if you use its unique content or ideas.
For example, if you are citing your own translation, APA style has a specific format you can follow. You can learn more about how to cite your own translations directly from the source. For other unique situations, the principle remains the same: provide a clear and honest trail for your reader. You would describe the work in the entry as accurately as possible (e.g., “Personal research journal,” “Author’s personal photograph,” etc.).
In my research journal, I noted that the plant’s leaves curled inward after exactly three days without water (Author’s Name, personal communication, May 15, 2023).
This makes it clear that the information comes from your own direct observation, which is a legitimate form of evidence in some contexts. The key is to be transparent about the nature of the source.
The Official Word from Style Guides
Don’t just take my word for it. The major academic style guides all agree that citing yourself is the correct procedure.
- MLA: The Modern Language Association points out that you should cite your own work just as you would cite any other piece to avoid plagiarism. They emphasize treating your previous writing as a valid source. Essayreply’s MLA citation guide covers the full works-cited format if you need it beyond self-citation.
- Chicago: The Chicago Manual of Style also advises that you cite a previous paper by describing it accurately, for example, as an “unpublished manuscript.” Essayreply’s Chicago citation guide has the complete note and bibliography format.
- APA: The American Psychological Association provides clear guidelines for citing various types of sources, including unpublished papers and even your own translations, ensuring you can handle almost any self-citation scenario. See essayreply’s APA citation guide for the full reference-list format.
When you think about it, citing yourself is a sign of a mature scholar. It shows you’re building on your own intellectual foundation, connecting past and present ideas to create something new and more profound. So cite away. But always ask your professor first.
Frequently Asked Questions
Here are quick answers to the questions readers ask most often on this topic.
Are you allowed to cite yourself?
Yes, you are generally allowed to cite yourself, and you absolutely should if you are citing or paraphrasing from a paper you have previously written. However, you must get permission from your instructor before reusing any part of a previous assignment for a new one. Each course assignment is usually expected to be original work done for that specific course.
How do you cite your own personal experience?
Citing personal experience is typically only appropriate for reflective or narrative essays, not formal academic research papers. If allowed, you don’t create a formal citation in the reference list. Instead, you frame it clearly within the text. For example: “During my time volunteering at the shelter, I observed…” or “From my personal experience, I can say that…” This makes it clear the information is from your own life and not an external source. You could also treat it as a “personal communication” if the style guide calls for it, but that’s less common. Always consult your instructor to ensure this type of evidence is acceptable for the assignment.
How do you cite yourself in APA format?
In APA 7, treat your own previous paper like any other source: author, year, and title in the reference list, with a matching in-text citation such as (Doe, 2023). If the paper was never formally published, label the reference entry [Unpublished manuscript] instead of a journal or publisher name. See Walden University’s guide to citing yourself in APA for worked reference-list examples.
How do you cite yourself in MLA format?
MLA 9 treats a self-citation the same as any other works-cited entry: your name, the title in quotation marks, the course or institution, and the year, followed by a parenthetical in-text citation. Self citation in MLA is not optional if you’re quoting or paraphrasing your own previous work, even when it was never formally published. Check essayreply’s MLA citation guide for the complete works-cited format.
