Windows Live Academic

Microsoft has debuted its answer to the literature search engine Google Scholar Released last month as a beta version, Windows Live Academic ferrets out articles and abstracts from more than 6000 journals and conferences. So far, the site only covers electrical engineering, computer science, and physics, but Microsoft plans to add more disciplines. Unlike Google Scholar, Windows Live Academic doesn't factor the number of citations into its rankings of articles, relying instead on each paper's quality and how closely it matches your search criteria. Microsoft's engine also offers more options for displaying the results, which you can sort by date, journal, author, or conference. But you'll still need subscriptions to access many of the articles.
