A. What is SCIRUS? “It is the most comprehensive scientific research tool on the web. With over 370 million scientific items indexed at last count, it allows researchers to search for not only journal content but also scientists' homepages, courseware, pre-print server material, patents and institutional repository and website information.” http://www.scirus.com/
B. Why Use Scirus? Scirus is a search engine specifically for science. It is designed to minimize the effort to find the best scientific information on the Internet. According to the publisher Scirus: Filters out non-scientific sites. For example, if you search on REM, Google finds the rock group - SCIRUS finds information on sleep, among other things. Finds credible information created in a variety of formats, such as PDF and PostScript files, which are often invisible to other search engines. Searches the most comprehensive combination of web information, preprint servers, digital archives, repositories, patent and journal databases. SCIRUS goes deeper than the first two levels of a Web site, thereby revealing much more relevant information. http://www.scirus.com/srsapp/aboutus/
