MEDLINE: NLM prepares for 2013 reload
Preparation for the annual reload of MEDLINE® on Dialog (Files 154,155) is underway. MEDLINE is reloaded every year because the National Library of Medicine (NLM) re-indexes relevant documents from the whole database with changed medical terms. Toward the end of November, the NLM provided updates that contained only RT=IN PROCESS and RT=IN DATA REVIEW records (no RT=COMPLETED records with Descriptors). In mid-December there will be a hiatus in the updating of MEDLINE on Dialog while adjustments are made to install the 2013 thesaurus after which daily updating will resume.
Subsequently, MEDLINE updating will continue unaffected through January/February 2013 while the backfile reload is processed. When the backfile reload is made available, descriptors in all records in the MEDLINE databases will match descriptors in the new 2013 version of the thesaurus.
Note: NLM did not provide updates from November 14-20.
