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

Author profile

Ongoing: cleanup of profiles person author
