# How to find peer-reviewed sources

Learn how to find peer-reviewed academic sources for university assignments using databases, filters, and verification checks.

Last updated: May 1, 2026

## How do you find peer-reviewed sources?

Use university library databases, apply peer-review filters, verify DOIs and journal credibility, and cross-check authors and institutions. Scholise searches 235M+ peer-reviewed papers across five academic databases with one query.

Peer-reviewed sources are evaluated by experts before publication in academic journals. They are the default evidence type for most university essays unless your brief specifies primary data or grey literature.

Start with your university library portal, it provides authenticated access to databases like Scopus, Web of Science, and discipline-specific collections. Library search interfaces often filter to peer-reviewed journals.

Use precise keywords and synonyms. Combine population + intervention + outcome in health research, or theory + context + method in social sciences. Boolean operators (AND, OR) narrow or broaden results.

Check journal credibility: look for established publishers, editorial boards, and absence of predatory journal red flags (aggressive fees, instant acceptance, vague peer review).

Verify each paper: confirm DOI resolves, authors exist at listed institutions, and the study design matches how you plan to cite it. Abstracts alone are insufficient for strong claims.

Track sources in a reference manager or project workspace from the first search, rebuilding bibliographies at the deadline causes formatting errors and missed citations.

Open-access filters help when you need full text quickly, but paywalled papers accessed through your library are equally citable.

## Frequently asked questions

Is Google Scholar peer-reviewed?

It mixes peer-reviewed journals with preprints, theses, and reports. Always verify each result.

Are preprints peer-reviewed?

Usually not. Treat preprints as provisional unless your field accepts them explicitly.

Can I use textbooks?

Textbooks support background context; most essays require primary journal articles for core evidence.

How do I access paywalled papers?

Use your library login, interlibrary loan, or open-access versions via Unpaywall and institutional repositories.
