MedlinePlus Quality Guidelines

MedlinePlus is designed to help you find appropriate, authoritative health information. To do this, we provide access to information produced by the National Library of Medicine and the National Institutes of Health, such as searches of MEDLINE/PubMed, our database that indexes medical research literature, and ClinicalTrials.gov, the database of research studies from the National Institutes of Health. We also provide you with a database of full-text drug and supplement information, an illustrated medical encyclopedia, a medical dictionary, interactive health tutorials, and the latest health news.

In addition, MedlinePlus contains pages that link to other Web sites. For example, we have Health Topic pages on about 750 diseases and conditions from Alzheimer's Disease to West Nile Virus. We focus on organizing the full-text publications produced by the NIH Institutes and other Federal Government organizations. We also link to other Web sites. The quality guidelines we use in evaluating links to Web pages are listed below.
