Acceso a los recursos web gratuitos desde las bibliotecas

This article describes and analyses the systems currently used by libraries to provide their users with access to free web resources and it explores the major obstacles for identifying and retrieving these resources. The ways in which libraries organise web resources can be described by three models: making lists, creating databases, and incorporating them into the opac. This study concentrates on the description, identification and characteristics of the latter two approaches, focussing on major experiences with special attention given to the following features in each case: selection criteria, types of descriptions, indexing and classification systems, information retrieval methods, and maintenance policies. Finally, current trends are discussed and considerations are offered as to how Spanish libraries might approach the organisation of web resources.
