The World Factbook was prepared by the CIA for the use ofU.S. government officials, and its style, format, coverage, and content are primarily designed to meet their requirements.[3] It was also frequently used as a resource for academic research papers and news articles.[4] As a work of the U.S. government, it was in the public domain in the United States.
On February 4, 2026, the CIA announced thatThe World Factbook was discontinued. All versions were removed from the CIA's website immediately, which was disruptive for academic users such as theBoston University Questrom School of Business which was using it foropen-book tests. No explanation for the action was given.[5][6] Following the cancellation of theFactbook, British programmerSimon Willison managed to retrieve and download the lastZIP file archive of the website, released in 2020, before extracting it into a freely accessibleGitHub repository.[6][7]

The firstclassified edition ofFactbook was published in August 1962, and the first unclassified version in June 1971.[15]The World Factbook was first available to the public in print in 1975.[15] Until 2008 the CIA printed theFactbook; from then until its discontinuation, it was printed by the Government Printing Office[16] following a CIA decision to "focus Factbook resources" on the online edition.[17] In 2017, the printed book was officially discontinued.[18] TheFactbook was made available via theWorld Wide Web beginning October 1994,[19] receiving about six million visits per month in 2006;[4] it was also available for download.[20] The official printed version was sold[21] by theGovernment Printing Office andNational Technical Information Service. In past years, theFactbook was available onCD-ROM,[22]microfiche,[23]magnetic tape,[23] andfloppy disk.[23]
