Citing a working paper can feel like trying to label a mysterious container in the back of the fridge: it looks important, it has a date, someone clearly made it, but nobody is fully sure what category it belongs to. Is it a report? A preprint? A discussion paper? A draft? A future journal article wearing sweatpants? The good news is that citing a working paper is much easier once you know which style guide your assignment, journal, professor, or editor wants.
A working paper is usually an early version of academic research shared before formal publication. It may appear on a university website, a research institute page, SSRN, NBER, RePEc, CORE, a government archive, or a personal faculty profile. Because working papers are often revised, replaced, or later published in journals, your citation should help readers find the exact version you used. That is the golden rule: cite the version in front of you, not the version you hope it becomes someday.
This guide explains three easy ways to cite a working paper in the most common academic formats: APA, MLA, and Chicago. You will see simple templates, realistic examples, in-text citation tips, and common mistakes to avoid. By the end, your bibliography will look calm, organized, and significantly less like it was assembled during a caffeine emergency.
What Is a Working Paper?
A working paper is a research document that is publicly available but not always formally published in a peer-reviewed journal. It may be released by a university department, think tank, research center, government office, economics bureau, policy institute, or scholarly repository. Working papers are common in economics, public policy, education, law, business, and social science research because scholars often want feedback before final publication.
Other names for similar documents include discussion paper, research paper, staff paper, policy paper, preprint, preliminary draft, or gray literature. These labels matter because they help readers understand the status of the source. A peer-reviewed journal article has usually completed editorial review. A working paper may still be under development, even if it is written by brilliant people with impressive office bookshelves.
Before You Cite: Gather These Details
Before choosing APA, MLA, or Chicago style, collect the citation ingredients. A working paper citation usually needs the author, year, title, working paper number if available, series name or institution, publisher or sponsoring organization, and DOI or URL. If the paper has a version number, revision date, or repository name, write that down too.
Quick Citation Checklist
- Author or organization name
- Year of publication or posting
- Full title and subtitle
- Working paper number, discussion paper number, or report number
- Institution, department, series, or repository
- DOI, stable URL, or direct PDF URL
- Version date, if the paper has multiple versions
If you are missing one detail, do not panic. Citation style guides are built for real-world sources, and real-world sources occasionally forget to wear matching socks. Use the information available, stay consistent, and make the citation easy for readers to trace.
1. Cite a Working Paper in APA Style
APA style is widely used in psychology, education, business, health sciences, and social sciences. For many working papers, APA treats the source much like a report or gray literature document. That means the citation should identify the author, year, title, working paper number if available, publisher or institution, and DOI or URL.
APA Reference List Template
Author, A. A. (Year). Title of working paper in sentence case (Working Paper No. 123). Publisher or Institution. DOI or URL
If the working paper does not have a number, you can identify it as a working paper in brackets after the title when needed:
Author, A. A. (Year). Title of working paper in sentence case [Working paper]. Publisher or Institution. URL
APA Example
Example reference:
Johnson, M. R., & Lee, T. K. (2024). Remote work and urban housing demand (Working Paper No. 48). Center for Urban Economics. https://example.edu/workingpapers/48
Parenthetical in-text citation: (Johnson & Lee, 2024)
Narrative in-text citation: Johnson and Lee (2024) argue that remote work may shift housing demand toward smaller metropolitan areas.
APA Tips for Working Papers
Use sentence case for the title, meaning you capitalize the first word, proper nouns, and the first word after a colon. Italicize the title of the working paper. If the author and publisher are the same organization, you usually do not need to repeat the publisher name. If a DOI is available, use it instead of a normal URL because it is more stable. If the paper is likely to change or disappear, use the most direct and stable link you can find.
APA is especially helpful when your paper discusses research findings and dates matter. Since working papers can be updated, the year tells readers which version you consulted. If the working paper later becomes a journal article, cite the journal article only if that is the version you actually used. Otherwise, cite the working paper. Your bibliography is not a crystal ball.
2. Cite a Working Paper in MLA Style
MLA style is common in literature, languages, humanities, cultural studies, and some interdisciplinary courses. MLA focuses on flexible “core elements” rather than forcing every source into a rigid category. For a working paper, the key is to list the author, title, container or repository, date, location, andwhen necessaryan optional note that identifies the source as a working paper.
MLA Works Cited Template
Author Last Name, First Name. “Title of Working Paper.” Repository or Series Name, Publisher or Institution, Year, DOI or URL. Working paper.
If you already identify the source as a working paper in your sentence, the final “Working paper” note may not be necessary. However, adding it can be useful when the source type is not obvious.
MLA Example
Example works cited entry:
Johnson, Maria R., and Thomas K. Lee. “Remote Work and Urban Housing Demand.” Center for Urban Economics Working Paper Series, 2024, https://example.edu/workingpapers/48. Working paper.
In-text citation: (Johnson and Lee 14)
If the working paper has no page numbers, cite the author’s name in the text or use only the author in parentheses:
No-page example: (Johnson and Lee)
MLA Tips for Working Papers
MLA titles are usually written in title case and placed in quotation marks when the working paper is treated as a short work inside a larger container, such as a repository or series. The container, such as a working paper series or archive, is italicized. If a DOI exists, include it. If not, use a stable URL or permalink.
MLA is a practical choice when you are writing about ideas, arguments, texts, or discourse rather than reporting numerical research in a heavily technical format. It also gives you room to explain the status of the source in prose. For example, you might write, “In a working paper hosted by the Center for Urban Economics, Johnson and Lee examine remote work and housing demand.” That single sentence tells readers that the source is preliminary without making your Works Cited entry carry all the emotional baggage.
3. Cite a Working Paper in Chicago Style
Chicago style is popular in history, arts, humanities, publishing, and some social sciences. It has two main systems: Notes and Bibliography, and Author-Date. Notes and Bibliography uses footnotes or endnotes, while Author-Date uses parenthetical citations similar to APA. For working papers, Chicago generally wants enough information for readers to identify and retrieve the source.
Chicago Notes and Bibliography Template
Footnote:
1. First Name Last Name, “Title of Working Paper,” working paper, Institution or Series, Year, page number, DOI or URL.
Bibliography:
Last Name, First Name. “Title of Working Paper.” Working paper, Institution or Series, Year. DOI or URL.
Chicago Notes and Bibliography Example

In-text citation: (Johnson and Lee 2024, 14)
Chicago Tips for Working Papers
Chicago is flexible, but it rewards clarity. If the paper is published as part of a numbered series, include the series and number. If it is unpublished but publicly available, put the title in quotation marks and describe it as a working paper. If it is a stand-alone published report, the title may be italicized depending on how it is presented. When in doubt, choose the format that makes the source easiest to locate.
APA vs. MLA vs. Chicago: Which One Should You Use?
The easiest answer is: use the style your instructor, journal, publisher, department, or organization requires. Citation style is not a personality quiz. You do not choose Chicago because you enjoy footnotes with vintage charm, or APA because you like dates standing near authors like tiny academic security guards. You choose the style that matches the assignment.
If no style is assigned, APA is often a safe choice for social science, education, business, psychology, and policy research. MLA is best for humanities and literary analysis. Chicago works well for history, publishing, and research that benefits from explanatory notes. For economics and public policy, check the target journal or institution because working papers are common in those fields and local preferences can vary.
Common Mistakes When Citing a Working Paper
Mistake 1: Citing the Journal Article You Did Not Read
Sometimes a working paper later becomes a peer-reviewed article. That does not mean you should cite the article automatically. If you used the working paper, cite the working paper. If you used the final article, cite the article. If you used both, cite both when they support different points.
Mistake 2: Forgetting the Working Paper Number
Many working papers belong to numbered series. That number is not decoration. It helps readers locate the exact document, especially when a research center publishes hundreds of papers with similar titles. Include the working paper number whenever it appears on the document.
Mistake 3: Using a Messy URL
A long tracking URL filled with question marks, session IDs, and digital confetti is not ideal. Use a DOI, stable URL, permalink, repository page, or direct PDF link. The cleaner the link, the happier your reader.
Mistake 4: Hiding the Source Type
If the document is preliminary, say so. Labeling it as a working paper, discussion paper, or preprint helps readers evaluate the source appropriately. This does not make the source weak. It makes your citation honest.
Mistake 5: Mixing Styles
Do not start in APA, flirt with MLA, and finish in Chicago. That creates a bibliography with commitment issues. Pick one style and apply it consistently across all sources.

How to Mention a Working Paper in Your Writing
Your in-text citation should not do all the work alone. A good signal phrase can help readers understand what kind of source you are using. For example:
Clear sentence: In a 2024 working paper for the Center for Urban Economics, Johnson and Lee argue that remote work may reshape housing demand in mid-sized cities.
This sentence tells readers the year, the source type, the institution, the authors, and the main idea. That is a lot of useful context packed into one sentence without sounding like a robot swallowed a bibliography.
Extra Experience: Lessons From Real Citation Work
After working with many academic drafts, student essays, policy briefs, and research-heavy blog posts, one lesson appears again and again: citations are not just formatting chores. They are part of the reader experience. A clean citation tells your reader, “I did the homework, I know where this came from, and you can check it too.” A sloppy citation says, “Somewhere on the internet, a PDF once happened.” Guess which one inspires more trust?
Working papers are especially tricky because they live in the middle zone between unpublished draft and formal publication. I have seen writers cite the same working paper three different ways in one document: once as a journal article, once as a website, and once as a report. None of those choices came from laziness. They came from uncertainty. The title page said “working paper,” the repository page looked like a website, and Google Scholar displayed it as if it were almost an article. The fix was simple: return to the document itself and cite the version actually used.
Another common experience is the “newer version surprise.” A student downloads a working paper in February, writes a literature review in March, and submits in April. Meanwhile, the authors upload a revised version with a different title, added coauthor, and changed page numbers. Suddenly, the citation looks wrong even though it was correct when the student found it. This is why stable URLs, working paper numbers, and version dates matter. They are not fussy details; they are little anchors in the stormy sea of academic revisions.
For writers creating web content, working papers can be valuable because they often discuss fresh research before it reaches journals. However, freshness comes with responsibility. When using a working paper in a public article, it is smart to mention that the research is preliminary. That does not weaken your content. It shows intellectual honesty. Readers appreciate transparency, and search engines increasingly reward content that demonstrates care, accuracy, and expertise.
My practical rule is simple: build the citation before writing the paragraph. This sounds backward, but it prevents chaos. When you create the reference first, you immediately notice missing details: no year, no institution, no working paper number, no DOI. Then you can solve the problem early instead of discovering it at midnight when your bibliography looks like a raccoon organized it.
Finally, keep a small citation note for yourself. Write down where you found the paper, when you accessed it, whether it had a DOI, and whether it described itself as a working paper, discussion paper, or preprint. You may not include all of that information in the final citation, but it will save you time if your editor, professor, or future self asks, “Where exactly did this come from?” Future you deserves kindness. Future you also deserves coffee.
Conclusion
Citing a working paper is not difficult once you identify the style and gather the right details. In APA, treat most working papers like reports or gray literature, with author, year, title, number, institution, and DOI or URL. In MLA, use the core elements and label the document as a working paper when needed. In Chicago, provide enough publication information for readers to locate the exact source, whether you are using notes or author-date citations.
The most important rule is accuracy. Cite the version you actually read, include the working paper number when available, use stable links, and be clear about the source type. Do that, and your citations will not merely look correct; they will help readers follow your research trail without needing a detective hat.
