IOP journals operate the single-blind review process, in which referees know the identity of the authors but authors do not know the identity of the referees. While all our journals operate the single-blind review process, our flagship open access journal New Journal of Physics and our ‘Express’ journals (Materials Research Express, Plasma Research Express, Engineering Research Express, and Biomedical Physics & Engineering Express) also offer a double-blind peer review option. Authors who choose the double-blind option on submission to these journals remain anonymous to the referees throughout the review process. Authors are responsible for anonymizing their manuscript before submitting their paper. A checklist is available to help authors with this process.
From October 2019, three of our journals (JPhys Materials, Journal of Neural Engineering and Environmental Research Letters) are participating in a one year trial of transparent peer review. This trial enables the open publication, alongside a published article, of that article’s entire peer review content (reviewer reports, author responses and decision letters) in an easily discoverable and citable form. We hope that this greater transparency will improve the quality of the review process, as well as enhancing readers’ understanding of articles and giving more recognition to the work of peer reviewers. During this trial period, both authors and reviewers will have the option of opting out of transparent peer review should they wish to (and reviewers who do opt in may choose to remain anonymous): the peer review history will only appear for articles where the author and (all) reviewers opt in. IOP Publishing retains the right to make minor edits to reports to improve readability and ensure they are suitable for publication, and in exceptional circumstances to withdraw reports.
