All papers are subject to blind peer review. Submitted papers are first assessed by the editorial team for suitability before sending out to the reviewer. Reviewers evaluate the papers according to the following criteria: relevancy of the topic, clarity of the argumentation, quality and relevancy of literature and other source material, readability, quality of conclusion, quality of illustrations. This document includes the instructions that are provided to the reviewers.

To avoid an unneeded delay in the publication of appropriate manuscripts, we ask the referees to send their peer review back to the responsible series editor within one month. The responsible editor will then transfer the referee's comments to the author(s) who may accept or refuse the peers' comments. In the latter case, the author(s) must provide argumentation to the responsible editor who will make the final decision.

Reviewers must keep their reviews confidential and not share the manuscript with other parties prior to publication. Upon acceptance for publication, the full coordinates of the peer referee will be listed on the journal’s website, if the reviewer agrees to this. Reviewers will receive a free copy of the volume that contains the paper which they refereed. Reviewers will not be financially rewarded.
