Produced by the U.S. National Library of Medicine, the
MEDLINE database is widely recognized as the premier
source for bibliographic and abstract coverage of
biomedical literature.
MEDLINE encompasses information from Index Medicus,
Index to Dental Literature, and International Nursing Index,
as well as other sources of coverage in the areas of allied
health, biological and physical sciences, humanities and
information science as they relate to medicine and health
care, communication disorders, population biology, and
reproductive biology.

Medline

TMUL@2009
The Ovid MEDLINE database contains bibliographic
citations and author abstracts from more than 5,200
biomedical journals published in the United States
and in 70 other countries. The database contains well
over 16 million citations dating back to the mid1950's, including more than 130,000 populationrelated journal citations (unique to the former
POPLINE® database) that were added to MEDLINE
in October of 2002. Although coverage is worldwide,
most records are derived from English-language
sources or have English abstracts. Abstracts are
included for more than 75% of the records.

PubMed簡介

TMUL@2009
PubMed, a service of the National Library of
Medicine, includes over 19 million citations
for biomedical articles back to the 1950's.
These citations are from MEDLINE and
additional life science journals. PubMed
includes links to many sites providing full text
articles and other related resources.
PubMed簡介

TMUL@2009
PubMed provides access to bibliographic
information which includes MEDLINE as well as:
 The
out-of-scope citations (e.g., articles on plate
tectonics or astrophysics) from certain MEDLINE
journals, primarily general science and chemistry
journals, for which the life sciences articles are
indexed for MEDLINE.
 Citations that precede the date that a journal was
selected for MEDLINE indexing.
 Some additional life science journals that submit full
text to PubMedCentral and receive a qualitative
review by NLM.

Related articles之功能

TMUL@2009
Each citation in PubMed has a link that will retrieve a
pre-calculated set of PubMed citations that are closely
related to the selected article. Click on Related
Articles to the right of each citation to display the
related set of articles. PubMed creates this set by
comparing words from the title, abstract, and MeSH
terms using a powerful word-weighted algorithm.
Citations are displayed in rank order from most to
least relevant, with the "linked from" citation
displayed first.

Link Out之功能

TMUL@2009
LinkOut allows publishers, aggregators, libraries,
biological databases, sequence centers, and other
Web resources to display links to their sites on items
from the Entrez databases. These links can take you
to the provider's site to obtain the full-text of articles
or related resources, e.g., consumer health
information. There may be a charge to access the text
or information. The current list of LinkOut providers
is available.
