Referencing a PDF confuses many students because a PDF is a file format, not a source type. How you cite it depends on what the PDF actually contains — a report, a journal article, a book or a web document. This UK guide explains how to reference a PDF correctly in Harvard and APA, with examples and the mistakes to avoid.
First, Identify What the PDF Actually Is
The golden rule is to reference the source, not the file type. A PDF might be a government report, a company’s annual accounts, a scanned book chapter or a downloaded journal article. Work out which it is, then use the referencing pattern for that source type. You almost never write “PDF” in the reference itself; instead you cite the report, article or book as normal and, where relevant, note where you accessed it.
Referencing a PDF Report or Document
For an organisational or government report accessed as a PDF, Harvard style reads: Author or organisation (Year) Title of report. Available at: URL (Accessed: day month year). In APA 7 it is: Author. (Year). Title of the report (Report No. if any). Publisher. URL. Use the organisation as the author when no individual is named, and include the URL so the reader can locate the exact document.
Referencing a PDF of a Journal Article or Book
If your PDF is a journal article, reference it exactly as you would the article, including volume, issue and page numbers, adding the DOI or URL. If it is a scanned book or book chapter, use the book or chapter format with the usual author, title, publisher and year. In both cases the fact that you read a PDF is irrelevant to the reference — what matters is citing the underlying published work accurately.
Common Mistakes When Referencing a PDF
The biggest mistake is writing “(PDF)” as though the format were the source. Others include omitting the author or organisation, forgetting the access date in Harvard, citing a random re-upload instead of the official version, and leaving out page numbers when quoting. Always trace a PDF back to its original publisher where possible, as this is more authoritative and more stable than a third-party copy.
Frequently Asked Questions
Do I write “PDF” in my reference?
Usually not. You reference the underlying source — a report, article or book — and include the URL where you accessed it. The file being a PDF does not change the citation.
How do I reference a PDF with no author?
Use the organisation responsible for the document as the author. If there is no organisation, move the title into the author position, exactly as you would for a website.
Do I need the access date for a PDF?
In Harvard, include the access date for online PDFs. In APA 7, a retrieval date is only needed for content designed to change over time.
