Peter Binfield has published "PeerJ—A Case Study in Improving Research Collaboration at the Journal Level" in the latest issue of Information Services & Use.
Here's an excerpt:
PeerJ Inc. is the Open Access publisher of PeerJ (a peer-reviewed, Open Access journal) and PeerJ PrePrints (an un-peer-reviewed or collaboratively reviewed preprint server), both serving the biological, medical and health sciences.
The Editorial Criteria of PeerJ (the journal) are similar to those of PLOS ONE in that all submissions are judged only on their scientic and methodological soundness (not on subjective determinations of impact, or degree of advance). PeerJ's peer-review process is managed by an Editorial Board of 800 and an Advisory Board of 20 (including 5 Nobel Laureates).
