Microsoft has beta released a new search engine for academic journal content called Windows Live. According to a press release, the initial beta release will target the subjects of computer science, electrical engineering and physics, although they plan to bring new subjects online in the near future.
It seems that Microsoft, like Google Scholar, has an arrangement with OCLC to integrate WorldCat content into Windows Live thereby indexing scholarly content, such as articles and books, which is available at a local library. Marketing libraries is a good thing.
