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, LocatorPlus/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
(Medical Literature Analysis and Retrieval System Online) is the U.S.
National Library of Medicine's (NLM) premier bibliographic database that contains
over 14 million references to journal articles in life sciences with a
concentration on biomedicine.
The NLM Catalog
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. Updated every weekday, the NLM Catalog provides links to
the library's holdings in LocatorPlus.
LocatorPlus is the web-based online public access catalog component of
the Voyager integrated library system used at NLM. It includes over
800,000 catalog records for books, audiovisuals, journals, computer
files, and other materials in the Library's collections.
Bookshelf
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®
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
is a bibliographic database covering teratology and other aspects of
developmental and reproductive toxicology.
Meeting Abstracts is the National
Library of Medicine's online collection of abstracts from HIV/AIDS,
Health Services Research, and Space Life Sciences meetings.
MedlinePlus
is the National Library of Medicine's web site for consumer
health information. MedlinePlus includes:
- over 650 health topics with links to health information from NIH
and other sources and also include a MEDLINE® 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.
- drug information for generic and brand name drugs.
- a medical encyclopedia containing an extensive library 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,
resources beyond MedlinePlus covering special topics and collections,
and directories of doctors, dentists and hospitals.
ClinicalTrials.gov provides patients, family members, health care
professionals, and members of the public easy access to information on
clinical trials for a wide range of diseases and conditions.
DIRLINE
(Directory of Information Resources Online) is the National
Library of Medicine's online database containing location and descriptive
information about a wide variety of information resources including
organizations, research resources, projects, and databases concerned
with health and biomedicine.
Genetics Home Reference is the National Library of Medicine's Web site
for consumer information about genetic conditions and the genes or chromosomes
responsible for those conditions. Information includes Genetic Condition
Summaries, Gene Summaries, Chromosome Summaries, a Help Me Understand Genetics
Handbook, and a searchable Glossary.
Household Products Database is a consumer's guide that provides
information on the potential health effects of chemicals contained in
more than 5,000 common household products used inside and around the
home. This database allows scientists and consumers to find out about
ingredients in brand-name products.
HSRProj
is a database providing access to ongoing grants and contracts in health
services research. It contains descriptions of research in progress funded
by federal and private grants and contracts for use by policy makers, managers,
clinicians and other decision makers.
OMIM
(Online Mendelian Inheritance in Man) is a continuously updated catalog of
human genes and genetic disorders. OMIM is based upon the text
Mendelian Inheritance in Man.
HSDB
is a toxicology data file focused on the toxicology of potentially
hazardous chemicals. It is enhanced with information on human exposure,
industrial hygiene, emergency handling procedures, environmental fate,
regulatory requirements, and related areas.
IRIS
(Integrated Risk Information System) is a toxicology data file
containing data in support of human health risk assessment.
ITER
(International Toxicity Estimates for Risk) is a toxicology data file
containing data in support of human health risk assessment.
GENE-TOX
is a toxicology data file containing genetic toxicology (mutagenicity) test data,
resulting from expert peer review of the open scientific literature, on over
3,000 chemicals.
CCRIS
(Chemical Carcinogenesis Research Information System) is a toxicology
data file containing over 8,000 chemical records with carcinogenicity,
mutagenicity, tumor promotion, and tumor inhibition test results.
Profiles
in Science provides access to the archival collections of leaders in
biomedical research and public health. Many of the collections
have been donated to NLM and contain published and unpublished items,
including books, journal volumes, pamphlets, diaries, letters, manuscripts,
photographs, audiotapes, video clips, and other materials.
Gateway access to additional NLM retrieval systems will be included in
future development phases. Among the resources to be added to the Gateway are the
Images
from the History of Medicine.
