Over the last couple of decades, new technologies and calls for a better system have challenged traditional peer review at scientific journals. Plenty of journals still do things the old-fashioned way, more or less. But these days, several open-access journals are employing alternative procedures, aiming to make peer review more open and collaborative. While the success of these initiatives has varied, several of these journals have become major players.

More open methods of peer review offer advantages and disadvantages for both authors and reviewers.

Part 1, "How Interactive Peer Review Works," is an introduction to the process.  

Part 2, "Advantages for Authors," points out how authors benefit from interactive peer review.

Part 3, "For Authors, Potential Downsides," examines the difficulties and risks that authors face while participating in interactive peer review.

Part 4, "What’s In It for Reviewers?," brings to light the benefits that reviewers gain from the interactive peer-review process.
