Imagine searching the Internet and being able to restrict your results to academic texts. Today Google launched a free search engine that aims to do just that. Google Scholar searches only journal articles, theses, books, preprints, and technical reports across any area of research. A test version of the search engine is available at http://scholar.google.com, so you can try it out. In a search for the phrase "human genome", for example, a normal Google web search throws back 450,000 or so hits, with genome centres and databases and other websites ranked top.
