Physics

Updated weekly. Indexes the research literature of physics; electrical engineering and electronics; & computers and control. Offers over 15 million records and strong international coverage. The archive portion, which was formerly separate, is now integrated with the current file.

Updated weekly. The Web of Science Core Collection is a group of databases (Science Citation Index Expanded, 1900-present; Social Sciences Citation Index, 1900-present; Arts & Humanities Citation Index, 1975-present) that together cover more than 21,000 journals across all disciplines. The Emerging Sources Citation Index (2005-present) tracks thousands of additional journals that are being considered for inclusion in the main citation indexes. Other files track references from conference proceedings (1990-present) and citations to books (2005-present).

The Web of Science platform currently also provides temporary access to several databases that are not part of the Core Collection, including Biosis Citation Index, Data Citation Index, and Zoological Record.

Created by Paul Ginsparg at the Los Alamos National Laboratory, Los Alamos, New Mexico and launched in 1991, arXiv.org (formerly xxx.lanl.gov) is a fully automated electronic archive and distribution server for research papers. Areas covered include physics and related disciplines, mathematics, nonlinear sciences, computational linguistics, and neuroscience.
