OVID Medline簡介

The Ovid MEDLINE database contains bibliographic
citations and author abstracts from more than 4,600
biomedical journals published in the United States and in
70 other countries. The database contains well over 12
million citations dating back to the mid-1960's, including
more than 130,000 population-related 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

PubMed, a service of the National Library of
Medicine, includes over 14 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

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

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

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.
