Subject: PubMed: MEDLINE Retrieval on the World Wide Web
From: Francis Oullette <francis@ncbi.nlm.nih.gov>
Date: Thu, 10 Jul 1997 17:33:02 -0400

NOTE: As of June 26, the National Library of Medicine (NLM) is providing
free WWW access to its MEDLINE database (see http://www.nlm.nih.gov for
further information).

Below is the text of the NLM Fact Sheet announcing the PubMed WWW retrieval
system (http://www.ncbi.nlm.nih.gov/PubMed).


              MEDLINE Retrieval on the World Wide Web

PubMed is a World Wide Web retrieval service developed by the National
Library of Medicine (NLM).  PubMed provides access, free of charge, to
MEDLINE, a database of nearly 9 million bibliographic citations and
abstracts in the fields of medicine, nursing, dentistry, veterinary
medicine, health care systems, and preclinical sciences.  PubMed also
contains links to full text versions of articles at participating
publishers' Web sites.  PubMed also provides access and links to the
integrated molecular biology databases maintained by the NCBI.  These
databases contain DNA and protein sequences, genome mapping data, and
3-D protein structures.  Additional NLM bibliographic databases, such
as AIDSLINE, will be added to PubMed.


MEDLINE is the NLM's premier bibliographic database, containing
citations and author abstracts from over 3800 biomedical journals
published in the United States and in 70 foreign countries.  Coverage
extends back to 1966 and new material is incorporated weekly.  All
citations in MEDLINE are assigned subject headings from the MeSH
vocabulary to assist users in their searches.

Searching PubMed

PubMed is an easy-to-use search tool for finding journal articles of
interest in the health and medical sciences.  A basic search screen
allows users to search by entering a few key words or phrases.  A set
of article titles is retrieved and their associated abstracts can be
selected for viewing.  A unique feature of PubMed is the ability to
find all related articles to a given article instantly.  Related
articles are pre-computed based on textual similarity.

Advanced search modes offer the ability to perform more complex
searches by specifying data fields and by using Boolean logic to
combine multiple search terms.  A special clinical query page provides
customized searches for studies based on etiology, diagnosis,
prognosis, or treatment of a particular disease.  Search results can be
viewed in various formats, including formats suitable for downloading
into bibliographic reference manager software.

For journals participating in the PubMed project and which have Web
sites, there are links to the full-text of retrieved articles.  Note
that these links are made to the Web sites of participating publishers
and may require users to register before being able to view the
full-text.  Currently there are 24 full-text journals participating.

The URL for PubMed is:


Publisher Participation

Publishers with WWW sites that provided access to the full-text of
their journals are invited to participate in PubMed if their journals
are already indexed in MEDLINE.  Participating publishers supply NLM
with formatted citations and abstracts prior to or at the time of
publication.  In turn NLM creates the PubMed links to the articles at
the publishers' sites.  NLM also provides citation matching in order to
link the citations in the reference section of an article directly back
to citations in MEDLINE.
