MEDLINE® Data Entry by Fiscal Year
Printer-friendly VersionBeginning in 1997, NLM has managed a dramatic shift in how citation data first enters the MEDLINE process: from double keyboarding citations by hand; to scanning and using optical character recognition (OCR); to importing records supplied by publishers in eXtensible Markup Language (XML) format. The data below reflects citations created (not necessarily indexed) for MEDLINE in each fiscal year.

The U.S. Government Fiscal Year runs from October 1 - September 30.
1Keyboarding ceased as a method of data entry in June 2004.
2There was a data entry and concomitant indexing backlog resulting from the General Services Administration Board of Contract Appeals' suspension of NLM's 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.
3Number derived from citations present in the database in 2007 that are tagged as being created during FY1995; not the original processing statistic.
