PubMed

PubMed was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM), located at the U.S National Institutes of Health (NIH). PubMed was designed to provide access to citations from biomedical literature. LinkOut provides access to full-text articles at journal web sites and other related Web resources.

Publishers participating in PubMed electronically submit their citations to NCBI prior to or at the time of publication. If the publisher has a web site that offers full-text of its journals, PubMed provides links to that site as well as biological resources, consumer health information, research tools, and more. There may be a charge to access the text or information.

PubMed Coverage

PubMed provides access to bibliographic information that includes MEDLINE, OLDMEDLINE, 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.

MEDLINE

MEDLINE is the NLM's premier bibliographic database covering the fields of medicine, nursing, dentistry, veterinary medicine, the health care system, and the preclinical sciences. MEDLINE contains bibliographic citations and author abstracts from more than 4,800 biomedical journals published in the United States and 70 other countries. The database contains over 12 million citations dating back to the mid-1960's . Coverage is worldwide, but most records are from English-language sources or have English abstracts.

OLDMEDLINE

OLDMEDLINE currently contains approximately 2 million citations to articles from international biomedical journals from 1950 through 1965. NLM expects to continue converting citations from its older print medical indexes and to add these citations to PubMed. OLDMEDLINE citations have not been updated with MeSH Terms and they do not contain abstracts. There are variations among OLDMEDLINE citations in the data elements present in the citation as well as in their format, depending on the original source from which the citation was obtained.

PubMed Journal Information

The Journals Database can be searched using the journal title, the Title Abbreviation, the NLM ID (NLM's unique journal identifier), the International Organization for Standardization (ISO) abbreviation, and the print and electronic International Standard Serial Numbers (pISSNs and eISSNs).

GRN & PubMed

Many journal articles in the GRN KnowledgeCentre use the LinkOut feature of PubMed for access to journal full-text.
