MEDLINE Data Entry by Fiscal Year [Updated for Inclusion of FY2014 Statistics]

Beginning in 1997, NLM has managed a dramatic shift in how citation data first enter 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 reflect citations created (not necessarily indexed) for MEDLINE in each fiscal year.
