As mentioned in this paper, DELOS collected into the DELOS Digital Library about 1200 documents (ranging in time from 1993 to 2008) related to Digital Libraries and in some way related to the DELOS activities. Unfortunately, during the last migration to a more current system, access online to the library has become problematic. If you are interested in a copy of some of the DELOS publications (especially the internal reports and notes, not published elsewhere), please send an email to one of the authors: name@isti.cnr.it .
