Google searching for scientific articles, e.g. mass spectrometry. It returns a list of articles ranked by citation number. Direct links to PDF files are provided where available, but availability seems to include any web site that has a copy of the article archived (including many educational sites). Early users can enjoy the Napster-like freedom that will last until shortly after the major journal publishers catch on.
