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
INSPIRES History
1963: HEPindex by DESY (book of publication references)
1974: SPIRES-HEP started @ SLAC in collaboration with DESY
Mid 80’s: remote access of SPIRES via email
more databases: CONF, EXP, INST, HEPnames, JOBS
Fermilab joined
Mar. 89: Information Management: a proposal -> WorldWideWeb
Dec. 91: first web-server outside of Europe
close collaboration with arXiv
Nov. 2011: INSPIRE replaced SPIRES
collaboration of CERN, DESY, Fermilab, SLAC
Apr. 2012: SPIRES front-end shut-off
Aug.2013: back-end moved to INSPIRE
Mai 2014: IHEP joined

4* Search Syntax INSPIRE
Google: Aad Higgs photon
searches everywhere in metadata
SPIRES: fin a aad, g and t higgs and k photon
use stop-words to structure search
INSPIRE: author:”aad, g*” title:higgs keyword:photon
use blank to separate search terms, needs quotes
MARC: 100__a:”aad, g*” 245__a:’higgs’ 6531_a:/photon/
“search sting”: full string
‘search string’: substring – may take very long
/search text/: substring, regular expressions possible
Be careful when you mix SPIRES with other syntax
