American Physical Society
Founded in 1899, the American Physical Society now has more than 41,000 members worldwide and publishes some of the world's leading physics research journals: the Physical Review series, Physical Review Letters, and Reviews of Modern Physics. Information about their journals, advance listings of accepted papers, and tables of contents are available on the Web pages.
The American Institute of Physics is one of the major publishers of physics information. In addition to their complete book and journal catalog, the Web page also includes tables of contents from the latest issues of more than 30 of their journals.
The SPIRES-HEP database, run by the Stanford Linear Accelerator Center (SLAC) since the late 1960's, covers the particle physics literature. In 1991 it became the first website in North America.
"AIP's Center for History of Physics works to preserve and make known the historical record of modern physics and allied sciences. Through documentation, archival collections and educational initiatives, the Center ensures that the heritage of modern physics is safeguarded and its story accurately told."
