About the HEP DatabaseSPIRES is hosted at SLAC, and operated in conjunction with DESY and Fermilab. We harvest papers of interest to HEP from various sources and add citation data, keywords, classifications and authors with their institutional affiliations. In particular we harvest from arXiv.org (about 50-60% of our papers), major journals in the field (most of these papers have already appeared on arXiv and we create a single record for them), conference proceedings, and a few other sources. SPIRES functions primarily as a gateway to all information in the field, providing context and consolidation for other data sources.
For our citations, we extract them (using a combination of automated and manual techniques) from arXiv papers, and we attempt to update the citations when they are updated on arXiv or when they are published. For conference proceedings and other literature not on arXiv or in journals, we generally do not track citations to or from these papers. We also make no effort to cover literature that is not of interest to the HEP community.
