SIAM has introduced Locus, SIAM's online journal archive that will be available beginning January 1, 2005, providing users with online access the complete archived collection of SIAM journals. Locus contains the electronic full text for every SIAM journal article published from the journal's inception through 1996. Locus articles are available as fully searchable PDFs, with full metadata available for each article. Articles published between 1980 and 1996 contain reference links to Mathematical Reviews and to the cited article via CrossRef (when available). Reference links back through the 1952 content will be added to Locus by 2007. Complete pricing, details, and information on SIAM's limited-time introductory offer can be found online.
