Google’s got a new service for searching journals, conference proceedings and other scholarly writings called (appropriately enough) Google Scholar. Nice clean interface, and like Citeseer they’re pointing not just to the official pay-for-download sites like the ACM and IEEE portal sites but also the free-for-download versions that authors usually put on their own sites (often in violation of copyright, but the last thing professional orgs want to do is piss of their own community).
