For additional information, please see the NLM Fact Sheet: Whats the Difference Between MEDLINE and PubMed?
MEDLINE MEDLINE is the NLM’s premier bibliographic database that contains references to journal articles in the life sciences with a concentration on biomedicine. A distinctive feature of MEDLINE is that the records are indexed with NLM’s Medical Subject Headings (MeSH). The database contains citations from 1949 to the present, with some older material. New citations that have been indexed with MeSH terms, publication types, GenBank accession numbers, and other indexing data are available daily (Tuesday through Saturday) and display with the tag [PubMed – indexed for MEDLINE]. See also the MEDLINE/PubMed Resources Guide. In Process Citations PubMed’s in-process records provide basic citation information and abstracts before the citations are indexed with NLM’s MeSH Terms and added to MEDLINE. New in-process records are available in PubMed daily (Tuesday through Saturday) and display with the tag [PubMed – in process]. Publisher-Supplied Citations Citations received electronically from
