About this Resource
This link provides easy access to numerous NLM resources that were formerly part of the NLM Gateway.
The NLM Gateway was a Web-based system that lets users search simultaneously in multiple retrieval systems at the U.S. National Library of Medicine (NLM). It allowed users of NLM services to initiate searches from one Web interface, providing "one-stop searching" for many of NLM's information resources or databases, including MEDLINE/PubMed and OldMEDLINE (journal citations from 1958 to 1965). The Gateway has been discontinued.
