"Healthweb: Linking you to the best in health information", is also a great site for clear and concise user guides. The guides cover MEDLINE access, Evaluating Health Information Sources, Searching the Internet, Document Delivery, and Bibliographic Software. This is a great resource that has been in existence since 1994, thanks to the NN/LM-GMR members' hard work. [ http://healthweb.org/ ]
