Scirus is a comprehensive science-specific search engine. Like CiteSeerX and Google Scholar, it is focused on scientific information. Unlike CiteSeerX, Scirus is not only for computer sciences and IT and not all of the results include full text. Like OpenGrey (System for Information on Grey Literature in Europe),it is a very important information source for grey literature, although unlike the latter, it also contains bibliographic details of peer-reviewed literature. It sends its scientific search results to Scopus, an abstract and citation database covering scientific research output globally. Scirus is owned and operated by Elsevier.
