The Web version of SciFinder enables access to the databases and many of the analytical tools provided by CAS (Chemical Abstracts Service) via a Web browser. The University of Delaware Library migrated from the SciFinder Scholar client software to SciFinder on the Web in August 2009.

SciFinder on the Web searches using text terms and has tools to refine and analyze search results. It is supported for both Mac and Windows users.

The databases include: CAplus (Chemical Abstracts), REGISTRY, CASREACT (chemical reactions database), CHEMCATS (commercially available chemical information),CHEMLIST (regulated chemical information), and MEDLINE (biomedical literature worldwide).


CAplus: 1907 to date, plus over 44,000 records for journal articles dated before 1907

MEDLINE: 1950 to date

REGISTRY: 1957 to date, plus many substances dating back to 1907

CASREACT: 1840 to date
