PubMed, Index Medicus, and NCBI
Since 1879, the NLM has published the Index Medicus, a monthly guide to articles in nearly five thousand selected journals. The last issue of Index Medicus was printed in December 2004, but this information is offered in the freely accessible PubMed amongst the more than fifteen million MEDLINE journal article references and abstracts going back to the 1960s and 1.5 million references going back to the 1950s.
The NLM also runs the National Center for Biotechnology Information (NCBI), which houses biological databases (PubMed among them) that are freely accessible on the Internet through the Entrez search engine.
