Open peer review

Open peer review  


Learn about the practice and benefits of open peer review, and steps to completing an open, signed, or published peer review.

What does it mean to practice open peer review? 

Open practice peer review is a broad term that encompasses any peer review model in which aspects of the process are made publicly available, either before or after publication.

For example, open peer review models may include any of the following transparent practices, either alone or in combination:

  • publishing peer review content
  • open commenting from the wider community
  • open discussion between authors, editors and reviewers
  • open review before publication through preprints
  • post-publication commenting
  • sharing author or reviewer identities
  • decoupling the peer review process from the publication process

It is important to treat each attribute of transparent review separately, since each can have a different impact on the author, reviewer, and reader experience. Here, we will be talking primarily about publishing peer review content, as well as touching lightly on signed reviews.

Published peer review history  

Published peer review history collects the correspondence exchanged during the peer review possess—including decision letters from each revision, complete with both editorial feedback and peer reviews, and the authors’ responses to reviewers—and makes it available alongside a published research article as a permanent part of the scientific record. PLOS authors can opt-in to publish their peer review history once their article is accepted for publication. If the reviewers have chosen to sign their review, their names will appear alongside their comments. If not, the reviews will appear anonymously.

The value of published peer review

Enriching the scientific record

Published peer review helps contextualize research and gives readers the benefit of additional expert opinions. Letting readers see the questions reviewers raised and how the authors mitigated them gives insight into the limits of the study. Publishing peer reviews also reinforces the validity of the article by exposing the rigorous vetting process it has undergone prior to publication.

Honoring reviews and reviewers

Choosing to publish peer reviews acknowledges the value of review, and the vital role that it plays in scientific communication by making it a permanent part of the scientific record. Offering reviewers the opportunity to sign is just one of several ways for them to claim credit for their work.

Educational tools

Making peer review publicly available creates a database of examples for students to reference as they begin to participate in peer review.  

How do I complete an open, signed, or published peer review?    

First, decide where you stand. Take some time to review the research, talk to colleagues you respect, and consider whether you want to sign your reviews as a general principle.

The practical aspects of completing a peer review remain the same, regardless of the review model a particular journal might happen to employ. There are three key stages to completing a peer review, open or otherwise.

Responding to invitations. Accept an invitation to review only if you have the necessary time and expertise, and can provide an objective review. Journals will let you know what peer review model they practice before you agree to review, usually in the invitation letter itself, or on their website.

Reading the manuscript. Before you read the manuscript, make sure that you understand the journal’s criteria, so you know what to watch for as you make your assessment. Read the manuscript through once for a general understanding, and a second time taking notes as you go. Pay special attention to the research question, methods, and conclusions, and review the figures and tables in conjunction with the results.

Writing the review. Begin with a summary of the research and your overall impression, before moving on to discuss specific areas for improvement and any other points. There is no need to do the authors’ work for them by suggesting line edits, specific manuscripts to cite, or experiments to do. Just let the editors know where you had questions or concerns.
