What is open peer review? A systematic review

Recognising the absence of a consensus view on what open peer review is, this article undertakes a systematic review of definitions of “open peer review”, to create a corpus of 122 definitions. These definitions are then systematically analysed to build a coherent typology of the many different innovations in peer review signified by the term, and hence provide the precise technical definition currently lacking.
Based on this work, Tony Ross-Hellauer proposes a pragmatic definition of open peer review as an umbrella term for a number of overlapping ways that peer review models can be adapted in line with the ethos of Open Science, including making reviewer and author identities open, publishing review reports and enabling greater participation in the peer review process.
