1966 and all that—when is a literature search done?

PubMed includes MEDLINE, which covers citations to articles dating back to the mid-1960s. A separate database, OLDMEDLINE, contains citations from roughly 1958-1965. Older citations are being added at a rate of approximately 1-2 years' worth per fiscal year. While most librarians are aware of O...

Summary:PubMed includes MEDLINE, which covers citations to articles dating back to the mid-1960s. A separate database, OLDMEDLINE, contains citations from roughly 1958-1965. Older citations are being added at a rate of approximately 1-2 years' worth per fiscal year. While most librarians are aware of OLDMEDLINE, many researchers may not be. Sheldon Kotzin, executive editor of MEDLINE, said that separate databases exist because of different original indexing standards. Older papers had many fewer subject headings, which do not correspond to currently used terms, and they have no abstracts. Kotzin told The Lancet that the Hopkins case has provided renewed interest in making OLDMEDLINE accessible through PubMed.
