UPDATE June 17th: PeerJ is now a fully participating journal, with access to all peer reviews and the right to send direct publishing offers to authors!
Peerage of Science is happy to be in collaboration with another publishing innovation:
The new open access journal PeerJ joins the list of journals welcoming links to Peerage of Science in their submissions. When peer review process in Peerage of Science is complete, authors can create a link (provided they have not already accepted a publishing offer inside the service) and give it to editor upon submission, e.g. in the cover letter. Editors may then use the Peerage of Science peer review, if they want.
PeerJ features a new kind of open access fee system, where authors currently have a choice of plans allowing publishing of one, two or unlimited number of PeerJ articles a year, for a single once-in-lifetime payment. Also, the journal is in many ways technologically "web-native". PeerJ is the first of its kind.
