Zeitschrift fur Fantastikforschung is a twice-yearly German journal on the fantastic and science-fiction, from the German Association for Research in the Fantastic.
They have just taken the journal open access and Creative Commons, although this doesn’t seem to cover the many volumes of back-issues which are available to purchase in paper. The first open access issue is now online.
They have a standing call for submissions, and appear willing to review published books in English. They’re also open to transcribed and translated interviews with major figures, such as one with Tad Williams.
