Latest News on Major Databases Launches/Updates

MEDLINE Annual Reload

The National Library of Medicine (NLM) is currently preparing for the annual MEDLINE reload.  The first stage is a temporary halt in the supply of fully indexed documents, which is scheduled as follows:

  • November 14, 2017: NLM expects to suspend temporarily fully-indexed MEDLINE citations. NLM will continue to add Publisher-supplied and in process citations
  • As consequence of this, searches and alerts using MeSH terms will not return results during this period
  • The number of documents returned by alerts during this period will be smaller than usual
  • Early December 2017: NLM expects to recommence all document types.  At that time, indexed documents will reflect 2018 MeSH

For information on the changes in the 2018 MeSH see
