Google has launched a new search service aimed at scientists and academic researchers. Google Scholar is a free beta service that allows users to search for scholarly literature like peer-reviewed papers, theses, books, preprints, abstracts and technical reports. The new service accesses information from resources such as academic publishers, universities, professional societies and preprint repositories. because the service automatically analyzes and extracts citations and presents them as separate results, users can find references to older works that may only exist offline in books or other publications.
