The editorial staff for Indie Publishing (a project of german trade magazine Buchreport) regularly publishes reviews of self and indie published titles in German language. Their target: to make authors heard that are having a hard time in a market dominated by large publishers. The editors decide which titles are reviewed – but authors and small publishers can always propose their books.
The service is free; the books must be available in printed form from any German bookstore (i.e. no Createspace-only editions). The reviews are then published in the “Indie-Katalog” that’s coming out in digital and printed editions. More informations: http://www.indie-publishing.de/home/indie_katalog.htm
