All our books have to appear in a series. We do not accept out-of-series books.
All our books receive two peer reviews. Peer reviews are anonymous, unless reviewers choose to open them.
We allow for different forms of optional open peer review: reviewers can disclose their identity, and they can also make their review available together with the published book. This helps recognize the work which has gone into the review. Reviewers have to explicitly state that they want their review to go public; if no such statement is made, the review remains closed.
All our books are published under the CC-BY license. In exceptional cases, we have published books under the CC-BY-SA and the CC-BY-ND license.
Our authors retain their copyright. We encourage the publication of preprints and postprints on author or university websites, repositories, or elsewhere. We appreciate links to the original publication.
