On Friday 30th January 2015, the Cochrane Library (http://www.cochranelibrary.com) will update the MeSH Thesaurus to the latest version. Search functionality should return accurate results on Sunday 1st February, 2015.
While the MeSH update is in progress, users may see a slight difference in some search counts until this processing is complete. The Cochrane Library are recommending that searches are not performed during this period.
Users are advised to review any searches containing MeSH terms, after the release to ensure that they have the correct MeSH term.
MeSH term changes are available at the NLM site at http://www.nlm.nih.gov/mesh/whatsnew.html.
The Cochrane Library apologies for any inconvenience caused during the time of the update.
