On 25 and 27 May 2012, the CERL Working group for bookbindings arranged two online events dedicated to different aspects of historical bookbindings. The working group’s overall objective is to promote the interest for and the knowledge of all aspects of historical bookbindings. One major issue is to complement traditional library cataloguing of bookbindings with more images, on-line resources and information as traditional library cataloguing is often not sufficient for discovery of this highly interesting heritage resource.
