The BAEP Group (Bibliotecas de arte de España y Portugal) has travelled a long way in the last ten years. It has undertaken numerous co-operative activities: conferences, training, publications, projects to produce union catalogues and organise exchanges between libraries, creation of a web site, and international collaboration. Despite these achievements the Group has not so far constituted itself formally and it now has to decide whether to continue as an independent society of art librarians or to attach itself to a more general library association.
