FAQ: Finding Medical Information in MEDLINE

Question: What is MEDLINE, and how do I use it to find information?



  • a huge database of more than 23 million references to articles published in approximately 5,600 current biomedical journals from the United States and over 80 foreign countries
  • a database you can search free using the NLM PubMed system at
  • for finding references on specific medical topics using either keywords or Medical Subject Headings (MeSH)
  • for references to articles published in the 1940's - to the present as converted from Current List of Medical Literature (CLML)

For more information, see:

  • MEDLINE Fact Sheet
  • MeSH Fact Sheet

If you do not have Internet access:

  • check to see if your local library provides access to MEDLINE
  • contact the National Network of Libraries of Medicine (NNLM) Regional Medical Libraries for suggestions if your local library cannot help you

We encourage you to discuss your MEDLINE search results with your health care provider.
