1Indexed citations are those citations selected for MEDLINE that have completed processing and indexing with current MeSH® (Medical Subject Headings®). Indexed citations have a status of MEDLINE. This number does not include OLDMEDLINE subset citations that are converted to MEDLINE status as part of the MeSH mapping project, effective FY 2007 forward.
2There was a data entry and concomitant indexing backlog resulting from the General Services Administration Board of Contract Appeals' suspension of the NLM editing and data entry contract from late February 1996 to late April 1996. The large backlog was eliminated in early April 1997. This caused fewer records to be added during FY 1996 and a greater number added in FY 1997.
