Abstract
(English)
This report introduces a digital library service, termed Collection Service, designed to support the dynamic creation of virtual collections of documents. Collections are created by specifying a set of descriptive criteria that express the information needs of a given community. The Collection Service provides two capabilities: on the one hand it constitutes a tool for dynamically structuring the information space according the needs of particular user/communities, on the other it supports the implementation of more efficient digital library services. The paper exemplifies this service by showing how it has been instantiated in the Cyclades digital library system and how it supplies support for efficient and effective query routing.
