The User Services Unit, NLM Reference and Web Services Section, Public Services Division, compiled this set of subject guides. The Guides are meant to serve as research starting points for health professionals, researchers, librarians, students, and others. Each guide lists a variety of resources, many of which are Internet accessible and free. The guides are not meant to be comprehensive but to introduce some of the major resources available on each topic.
The topics for these Subject Guides are drawn from the most frequently asked questions the Reference and Web Services staff encounters in e-mails and onsite. (Note expanded sub-topics in left margin.)
