Digital libraries represent the meeting point of a large number of technical - eas within the ?eld of informatics, i.e., information retrieval, document m- agement, information systems, the Web, image processing, arti?cial intelligence, human– computerinteraction,mass-storagesystems,andothers.Moreover,d- ital libraries draw upon other disciplines beyond informatics, such as library sciences, museum sciences, archives, sociology, psychology, etc. However, they constitute a relatively young scienti?c ?eld, whose life spans roughly the last 15 years. During these years the DELOS Network of Excellence on Digital - braries (http://www.delos.info) has represented a constant presence aiming to contribute to the consolidation of the ?eld.
