MEDLINE Now Includes Records from 1946

MEDLINE began as a project covering medical literature citations from 1966 forward. For a number of years NLM has been expanding that backwards, adding data from earlier records along with current subject headings (MeSH) to make the information searchable. Now the OLDMEDLINE subset has expanded back through 1946, adding 20 years to the original MEDLINE database. You will encounter these older records as needed via whichever version of MEDLINE you use (PubMed, EBSCO MEDLINE, or in some cases OVID).
