NLM is pleased to provide a series of statistical reports run on baseline MEDLINE/PubMed data. The reports are available as both PDF and Microsoft Excel files and the overall report on the 2004 baseline is also available in HTML format. NLM expects to make similar reports available after the conclusion of each production year.
Baseline Description
The 2004 baseline database was
produced in November 2003 at the conclusion of the 2003 MEDLINE production year
and after NLM performed its annual data maintenance, primarily to apply the 2004
MeSH Vocabulary to the MEDLINE records. The statistics do not cover new,
revised, or deleted records during the 2004 production year.
The baseline database includes all MEDLINE records (designated as MedlineCitation Status=Completed in the XML) as well as all records in PubMed-not-MEDLINE status (designated as MedlineCitation Status= PubMed-not-MEDLINE in the XML) at the time the baseline was created. It does not include the non-MEDLINE in-process status or in-data-review status records that NLM also distributes to MEDLINE licensees; nor does it include the publisher status records that reside in PubMed which are not distributed to licensees.
Documentation
An alphabetical list of the XML elements in
the baseline database is at http://www.nlm.nih.gov/bsd/licensee/elements_alphabetical.html.
Element documentation, including current definitions of the MedlineCitation
Status attribute values, is available at http://www.nlm.nih.gov/bsd/licensee/data_elements_doc.html#elements.(Note
that the xml elements change over time and some element names or values present
in these baseline files may not be currently in use).
