The BAS is updated quarterly, with batch posting of thousands of new entries each quarter. More background information is available at the BAS web site. Now are two digital resources now available. Science Online, which is updated weekly, offers abstracts and full text of every scientific paper and summaries and full text of every news article from the following day's issue. In addition, there are archives of abstracts and summaries back to May 1995 and full text is now being archived as well.
Users can search by issue, by keyword, and by author name.
Special features include searching back issues and ordering full text. Links from CDL-hosted abstracting and indexing databases to Science Online are in place. Science NOW, which is updated daily, posts several 2-3 paragraph reports on breaking news of a research or science policy nature. These news items cover events occurring anywhere in the world and in all scientific disciplines, and are written by staff, freelance editors, and writers working for Science in Washington, Cambridge, England, and elsewhere worldwide. CDL's licensing agreement with AAAS does not include access to Science's Next Wave, a career guidance resource for scientists.
