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. The activities ofDELOS startedmanyyearsago, with the "DELOSWorking Group" at the end of the 1990s, and the DELOS Thematic Network, under the Fifth Framework Program, from 2001 to 2003. Since the beginning, the main objective of DELOS has been to advance the state of the art in the?eld of digitallibrariesbycoordinatingthee?ortsofthemajorEuropeanresearchteams conducting activities in the major?elds of interest. EveryyearDELOSorganizesthe All-Tasksmeeting, the annualappointment of the DELOS community where the scienti?c results achieved during the p- vious year are presented. Instead of the usual status reports from the various DELOSTasks, in 2006it wasdecidedto issueaCallfor Papers, soliciting papers reporting the scienti?c achievements of the DELOS members during 2006, and to organize a conference. The?rst DELOS conference was held during February 13-14, 2007, at the Grand Hotel Continental in Tirrenia, Pisa, Italy
