The National Library of Medicine® (NLM®) is currently involved in MEDLINE year-end processing (YEP) activities. These include changing the Medical Subject Headings (MeSH®) and Supplementary Concept Substance Names on existing MEDLINE citations to conform with the 2009 version of MeSH, and other global changes.
Important Dates
-
November 19, 2008: NLM expects to temporarily halt the addition of fully-indexed MEDLINE citations to PubMed.
- Mid-December 2008: The PubMed MEDLINE citations, translation tables, and the MeSH database will have been updated to reflect 2009 MeSH.
For details about the impact on searching from November 19 to mid-December, see: Annual MEDLINE®/PubMed® Year-End Processing (YEP): Impact on Searching During Fall 2008.
For background information on the general kinds of changes made annually, see: Annual MEDLINE®/PubMed® Year-End Processing (YEP): Background Information.
