Medline

• Medline
• 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

• 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??

• 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.

11
PubMed??

• 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???

• 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???

• 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.
