PubMed Citations Now Date Back to a Time When Gas Cost 15 Cents

The National Library of Medicine has announced its inclusion of more than 60,000 articles indexed in the 1947 Current List of Medical Literature in the PubMed database. The original database, MEDLINE, launched in 1971, contained citations to journal articles published from around 1966 onward. "Some contemporary medical questions can only be answered by consulting the older literature," said NLM Director Donald Lindberg in a statement. "NLM is working to make the journal citations in older printed indexes electronically searchable, and our goal is to go back at least as far as World War II." According to the NLM, the additional citations bring the total of citations in MEDLINE/PubMed to more than 20 million.
