The SPIRES collection
As stated on the SPIRES about page
The SPIRES-HEP database has been run by the Stanford Linear Accelerator Center(SLAC) since the late 1960’s as a database of particle physics literature. SLAC also collaborates with other physics institutions around the world on SPIRES. In 1991 it became the first web-site in North America and now attracts around 50,000 searches per day from particle physicists.
The SPIRES records come to us from SPIRES via an informal agreement. As part of this agreement, we only take the SPIRES contents that is in the arXiv collection. We filter the post 1965-contents of the data.
The collection is updated on the third of every month.
