American Physical Society
The American Physical Society (APS) Journals package houses the current issues and archives (PROLA, which extends back to 1893 in one case) for the APS journals (mostly the Physical Reviews sections). The articles can be browsed (the interface does not contain a search interface; INSPEC is recommended for searching and will link to the APS journals), and are delivered in both page image and Adobe Acrobat Reader (.PDF) format.
