RÉFLEXION SUR LE RÔLE DES MÉTADONNÉES POUR UNE MEILLEURE DÉCOUVERTE.

The aim of this paper is to examine the impact of metadata on the identification of special collections, particularly games, in academic library discovery tools. Effective identification of these resources is closely linked to the quality of the metadata describing them, as well as to the technological characteristics of the system used.In order to optimize this identification, the cataloging of the games collection of the Laboratoire ludique de l'Université du Québec à Montréal has added the descriptors of the ESAR system, a controlled vocabulary specialized for games. A brief presentation of the ESAR system will be given to better understand its particularities compared to traditional thesauri and to better underline its interest for games indexing. These descriptors can now be encoded in MARC format in subject fields, thus opening up the possibility of fully exploiting their discovery potential. [ABSTRACT FROM AUTHOR]
