OLDMEDLINE is Another Year Older with the Addition of the 1946 CLML Citations.

OLDMEDLINE is Another Year Older with the Addition of the 1946 CLML Citations
More historical journal citations are now in MEDLINE®/PubMed® with the addition of over 48,000 citations from the 1946 Current List of Medical Literature (CLML). The National Library of Medicine® (NLM®) has been converting information from older print indexes that were the precursors to Index Medicus. When the original MEDLINE database made its debut in 1971, it contained citations to journal articles published from approximately 1966 forward. The 1946 CLML represents the 20th year going back in time to enhance access to the older biomedical literature. With the addition of the 1946 CLML citations, the OLDMEDLINE subset contains over two million citations.

NLM also continues the work of mapping the original keywords assigned to these older references so that current MeSH® terms (Medical Subject Headings) are added to the records and available for searching in PubMed.

Additional information about the OLDMEDLINE data project is available.
