Introduction
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. This audience may include physicians
and other health care providers, researchers, librarians, students, and
increasingly, patients, their families, and the public. Other users may
find the Gateway useful for an overall search of NLM's information
resources. Some searchers may locate what they need immediately, while
others will utilize the Gateway as an adjunct tool to other NLM search
services such as PubMed® and MedlinePlus®.
System and Data Coverage
The Gateway connects users with multiple NLM retrieval systems
and also provides a search interface for meeting abstracts. Please note,
other NLM systems (e.g., PubMed, NLM Catalog, MedlinePlus) will
retain their own search interfaces and will continue to be publicly
available.
The Gateway will provide access to the information found in an
increasing number of NLM retrieval systems in several phases. Currently,
users are able to access information from the collections in the table
below. The Meeting Abstracts collection is found only in the Gateway.

MEDLINE
(web site;
MEDLINE fact sheet;
PubMed fact sheet)
(Medical Literature Analysis and Retrieval System Online) is the U.S.
National Library of Medicine's (NLM) premier bibliographic database that contains
over 16 million references to journal articles in life sciences with a
concentration on biomedicine. PubMed provides free access to MEDLINE, and includes additional
citations such as in-process citations and OLDMEDLINE citations that have not yet been converted to
MEDLINE status.
The NLM Catalog
(web site;
overview)
is an alternative search interface to NLM bibliographic
records for journals, books, audiovisuals, computer software, electronic
resources, and other materials that is available to users under the NCBI
Entrez system.
Bookshelf
(web site;
overview)
is a growing collection of full text biomedical books, as well as additional
resources such as GeneReviews and Health Services/Technology Assessment Text (HSTAT).
TOXLINE®
(web site;
fact sheet)
is the National Library of Medicine's (NLM) bibliographic database for
toxicology, a varied science encompassing many disciplines. TOXLINE records
provide bibliographic information covering the biochemical, pharmacological,
physiological, and toxicological effects of drugs and other chemicals.
TOXLINE Subset complements TOXLINE Core (part of MEDLINE) with references
from an assortment of specialized journals and other sources.
DART
(web site;
fact sheet)
is a bibliographic database covering teratology and other aspects of
developmental and reproductive toxicology.
Meeting Abstracts
(overview)
is the National Library of Medicine's online collection of abstracts
from HIV/AIDS, Health Services Research, and Space Life Sciences meetings.
MedlinePlus
(web site;
fact sheet)
is the National Library of Medicine's web site for consumer
health information. MedlinePlus includes:
- health topics with links to health information from NIH
and other authoritative sources and also include a MEDLINE/PubMed®
search, current news items about the topic, and links to related topics.
Health topics include interactive health tutorials that use animated graphics
and sound to explain conditions and procedures in easy-to-read language.
- information for prescription and over-the-counter medicines, plus herbs.
and supplements
- a medical encyclopedia containing an extensive collection of medical
images as well as 4,000 articles about diseases, tests, symptoms, injuries
and surgeries.
- current health news with late-breaking stories about medicine and health.
- other resources including organizations providing health information,
consumer health libraries providing services to local residents, resources beyond
MedlinePlus covering special topics and collections,
and directories of doctors, dentists and hospitals.
