Electronic Resources Database of metadata for High Energy Physics search for articles Preprint repository, stores full-text Some search functionality arXiv.org Similar to INSPIRE, for Astrophysics ISI Web of Knowledge for published articles Thomson Reuters SCOPUS for published articles Elsevier Institutional repository for DESY publications statistics, full-text, search PUBDB DESY Publication Database

Articles are submitted by (DESY) authors Institutional repositories serve to document publications (how many papers written by group xyz) Offer / archive full-text (pre-print version – journal version has copy right) make publications freely accessible
