A label for peer-reviewed books

The Publishers Association of Flanders, Belgium, has created a label for peer-reviewed books: the Guaranteed Peer Reviewed Content (GPRC) label (www.gprc.be/en). We introduce the label and the logic behind it. A label for peer-reviewed books encourages transparency in academic book publishing. It is especially relevant for the social sciences and humanities and in the context of performance-based funding of university research.
