PubMed or MEDLINE?

What's the Difference Between MEDLINE®, PubMed® and PubMed Central?

  • PubMed Central is an archive of the full-text biomedical journal papers available online without a fee.   
  • MEDLINE is one part of PubMed. Approximately 5,400 journals published in the United States and more than 80 other countries have been selected and are currently indexed for MEDLINE. A distinctive feature of MEDLINE is that the records are indexed with NLM's controlled vocabulary, the Medical Subject Headings (MeSH®).

In addition to MEDLINE citations, PubMed also contains:

  • In-process citations which provide a record for an article before it is indexed with MeSH and added to MEDLINE or converted to out-of-scope status.
  • Citations that precede the date that a journal was selected for MEDLINE indexing (when supplied electronically by the publisher).
  • Some OLDMEDLINE citations that have not yet been updated with current vocabulary and converted to MEDLINE status.
  • Citations to articles that are out-of-scope (e.g., covering plate tectonics or astrophysics) from certain MEDLINE journals, primarily general science and general chemistry journals, for which the life sciences articles are indexed with MeSH for MEDLINE.
  • Citations to some additional life science journals that submit full text to PubMedCentral® and receive a qualitative review by NLM.
  • Citations to author manuscripts of articles published by NIH-funded researchers.
  • Citations for a subset of books available on the NCBI Bookshelf (a citation for both the book and each chapter or section of the book).
  • Medical Subject (MeSH) Terms

    MeSH is the U.S. National Library of Medicine's controlled vocabulary used for indexing articles for MEDLINE/PubMed. MeSH terminology provides a consistent way to retrieve information that may use different terminology for the same concepts. MeSH subject headings are used in the OhioLINK Book Catalog and in the PubMed and Medline article databases. 

     If you do not know a specific heading to search, you may find it more helpful to start with a Keyword search, or use the NLM MeSH Browser to explore available headings.
