How to Cite Paywalled Sources You Can't Fully Access

You have found the perfect source for your argument — but it is behind a paywall, available only as an abstract, or you have only ever seen someone else's description of it. Can you still cite it? Sometimes, and there is a correct way to do it.

The Fundamental Principle

Cite what you have read. A citation is a claim that the source says what you say it says, and you are vouching for it.

APA puts the same principle as an instruction: "Generally, writers should endeavor to read primary sources (original sources) and cite those rather than secondary sources (works that report on original sources)." It then adds the concession that matters here: "Sometimes, however, this is impossible."

Sources Behind Paywalls

Before you cite something you cannot read, work through the access routes:

• Check your library's holdings properly. A subscription is often invisible from a Google result; search your library's discovery layer or use its link resolver.
• Request it through interlibrary loan. Terms differ by institution — check your own library's page for cost and turnaround.
• Look for a preprint or an accepted manuscript in a repository, or on the author's institutional page.
• Email the author. Say what you are working on and which paper you need.
• Check whether alumni access, a professional body membership or a public research library gets you in.
• Ask your subject librarian. This is what they do, and they know routes that are not documented anywhere.

If you still cannot get the full text, you have two honest options: find a different source that supports the point, or use your style's indirect-source form.

Indirect (Secondary) Citations

When you are citing a work because another author described it, not because you read it, your style has a specific form for saying so.

APA

The rule: name the original source in your signal phrase, put the secondary source in the parentheses, and list only the secondary source — the one you read — in the reference list. Include the original's year if you know it.

The Purdue OWL's APA page illustrates this with generic placeholder names; the shape above is that rule with the placeholders made visible, so nothing here can be mistaken for a real reference.

MLA

MLA uses "qtd. in", and it lets the original author's name sit in your prose, inside the parenthetical, or in a note. These are the MLA Style Center's own published examples, with a real book behind them:

Works Cited — note that only Damrosch, the source actually read, appears:

That book is real: The Imaginative World of Alexander Pope by Leo (Leopold) Damrosch, University of California Press, 1987, checked in Open Library on 22 September 2026.

Chicago

Chicago's notes use "quoted in" or "cited in", with the work you read given in full.

The point of all three forms is the same: you are telling the reader that you did not read the original, so they know whose account they are trusting.

When Indirect Citations Are Acceptable

They are reasonable for background or historical context that is not load-bearing, for sources that are genuinely unreachable — out of print, untranslated, archive-only — and when the secondary author's interpretation is itself your subject.

They are a poor choice for a claim your argument rests on, for recent work you could plausibly obtain, and whenever you could reasonably get the original and did not try. Used often, they tell a reader you have been working from other people's reading lists.

Citing Abstracts Only

An abstract is written to get the paper read. It can omit limitations, compress methods past the point of accuracy, and state an effect without the conditions attached to it. A claim you build on an abstract may be wrong in a way the abstract cannot show you.

If an abstract is genuinely all you can get, say so in your text and treat it as indirect: you are reporting what the abstract states, not what the study established.

Retracted Papers

A retraction usually means something serious — fabrication, a major error, an ethics failure — and the paper's claims are no longer evidence for anything.

Do not cite a retracted paper as support for its findings. Do cite it when the retraction itself is your subject, or when you are describing the history of a controversy, and mark its status clearly so no reader mistakes your intention.

Style guides differ on the exact reference form for a retracted work and for a retraction notice, so follow the one your department requires rather than a generic pattern. What matters in every style is that the retraction is visible to the reader.

Check before you submit, not after:

• The Retraction Watch Database is searchable and free.
• The journal's article page carries the notice.
• The DOI's Crossref record carries an updated-by relation naming the retraction notice — that field is what most reference managers and checking tools read. Mind the direction: updated-by sits on the retracted paper and points at the notice, while the notice's own record carries update-to pointing back at the paper. Some publishers deposit only the notice, so if a paper's record looks clean, search the notice too. (A few records, where the publisher simply retitled the article "RETRACTED", carry update-to pointing at themselves.)

Papers With Corrections or Errata

A correction fixes a specific error; it does not invalidate the paper. Find the correction, check whether it touches the part you are citing, and cite the corrected information if it does. Mention the correction where it is substantive and relevant to your discussion. Styles differ on whether you cite the notice as well as the paper, so check yours.

The "I Can Only Find the Summary" Problem

Between AI summaries, abstract databases and citation tools, it has never been easier to encounter a source's claims without meeting the source. The temptation is obvious and the answer is unchanged: do not cite what you have not read.

If you cannot access a source, find another that makes the point, use the indirect form properly, or leave it out.

One genuine exception: in a systematic review or meta-analysis you may work from data extracted into an included study's report, provided your methods say that is what you did.

Practical Decision Tree

1. Can you reach the full text by any legitimate route? → Do that, and cite it normally.
2. Have you actually tried the library, ILL, a repository, the author and your librarian? → If not, keep going.
3. Is the source essential to your argument? → If yes, you need real access, not a workaround.
4. Can another source you can read make the same point? → Use it.
5. Must it be this source? → Use the indirect form, clearly marked, and say what you worked from.
