What Is Peer Review? How Academic Publishing Works

"Peer-reviewed" is the quality stamp of academic publishing. Understanding the process tells you why peer-reviewed sources are more trustworthy — and what peer review can and cannot guarantee.

The process, step by step

You submit a manuscript; an editor screens it; if it passes, it is sent to two or more independent experts (your "peers") who assess its rigour and originality. They recommend accept, revise, or reject. Most papers go through one or more rounds of revision before acceptance — or are rejected.

Types of review

In single-blind review, reviewers know the authors but not vice versa; in double-blind, neither side knows the other; in open review, both are known. Double-blind aims to reduce bias.

What it guarantees — and doesn't

Peer review checks that the work is methodologically sound, original, and clearly reported. It does not guarantee the findings are true or replicable — that comes from later studies. So "peer-reviewed" means "vetted by experts", not "proven".

How ProSearch helps

ProSearch searches peer-reviewed databases (OpenAlex, Semantic Scholar, CORE) and surfaces metadata like venue and citation count, so you can prioritise vetted, influential sources for your work.
