Are open access books peer reviewed?
Regardless of the mode of access (print, digital, open access), not all books are peer-reviewed. In order to see if an open access book publisher conducts peer review, the best course of action is to check if it is listed on the DOAB (2020a), which lists nearly 400 publishers and requires that academic books are “subjected to independent and external peer review prior to publication”. In addition, the OPERAS Certification Service will soon be available “to certify publishers at both the publisher level and the individual publications level” (DOAB, 2020b).
