Search

The libraries of the Catalan Polytechnic University (UPC) have a collection of cartographic documents made up mainly of navigation charts as well as numerous land maps. It has been noted that the OPAC search and retrieval on this latter group is complex and confusing. In order to resolve this problem, a digital cartographic gateway was developed. Its main function is as an image (or sensitive) map of Catalonia that permits retrieving the maps by county. The application, developed using Flash, Asp.Net and Dhtml, runs on a database taken directly from the UPC Libraries' Catalogue. The principle features of this application are the minimal maintenance required as well as the ease of updating. [ABSTRACT FROM AUTHOR]

The article presents the results of a field work carried out in 2003 to verify the tools of subject retrieval offered by public libraries in the city of Buenos Aires. It describes the vocabulary and the classification system used and also the possibilities of subject access by open stacks with a physical arrangement of the collection by subject, and online public access catalogs. It concludes with some recommendations to improve the efficiency of subject searching in public libraries. [ABSTRACT FROM AUTHOR]
