The Central Intelligence Agency (CIA) publishes The World Factbook in printed and Internet versions. The World Factbook originated as a classified book of information for agency use in the early 1960s, with the first unclassified versions made available to the public in 1975. The book and website both feature detailed information about every known country on earth.
