PubMed Tutorial from The Levy Library: PubMed NOT MEDLINE

PubMed (NOT MEDLINE) Content

PubMed provides access to MEDLINE and to other records that are not a part of the MEDLINE database.  

MEDLINE citations make up the majority (approximately 80%) of the PubMed, but PubMed includes other records that are not a part of MEDLINE. Records in PubMed that are not part of MEDLINE do not contain MESH terms. 

Among the PubMed records that are not part of MEDLINE are:

  • Citation records in PubMed that have not yet been indexed for MEDLINE. As of July 2015, over 110,000 citations are awaiting indexingThis includes the newest citations, ones that have not yet been processed.
  • Citations for manuscripts by NIH-funded researchers that are not published in MEDLINE journals
  • Citations for content in the NLM's PMCan open archive of full-text journal articles
  • About 4,000 records for selected books, book chapters and reports in the NCBI Bookshelf

Records in PubMed that are not part of MEDLINE do not contain MESH terms.
