Scirus

Scirus is a comprehensive science-specific search engine. Like CiteSeer and Google Scholar, it is focused on scientific information. Unlike CiteSeer, Scirus is not only for computer sciences and IT and not all of the results include full text. It also leverages its scientific search results to Scopus, an abstract and citation database covering scientific research output globally. Scirus is owned and operated by Elsevier.
