CERN, DESY, Fermilab and SLAC have announced that SPIRES (http://slac.stanford.edu/spires), the venerable and long-serving information system for High-Energy-Physics, is being replaced by INSPIRE (http://inspirebeta.net).
INSPIRE is jointly developed by CERN, DESY, Fermilab and SLAC, and builds on four decades of hand-curated SPIRES content and Invenio Digital Library software. It offers faster and smarter searches, detailed results, direct access to figures, co-cited articles and full-text searches. Many more features will be released in the next few months, in partnership with arXiv, ADS and leading publishers in the field.
You can preview the beta version of INSPIRE at http://inspirebeta.net
