The NLM Gateway  is a Web-based system that lets users search simultaneously in multiple retrieval systems at the U.S. National Library of Medicine (NLM). It allows users of NLM services to initiate searches from one Web interface, providing "one-stop searching" for many of NLM's information resources or databases. It is being developed by the  Lister Hill National Center for Biomedical Communications (LHNCBC) at the National Library of Medicine (NLM), a part of the   National Institutes of Health (NIH)

One target audience for the Gateway is the Internet user who is new to NLM's online resources and does not know what information is available there or how best to search for it.
