How often is The World Factbook updated?
Formerly our Web site (and the published Factbook) were only updated annually. Beginning in November 2001 we instituted a new system of more frequent online updates.
The annual printed version of the Factbook is usually released about midyear. US Government officials may obtain information about Factbook availability from their own organizations or through liaison channels to the CIA. Other users may obtain sales information through the following channels:

Can I use some or all of The World Factbook for my Web site (book, research project, homework, etc.)?
The World Factbook is in the public domain and may be used freely by anyone at anytime without seeking permission. However, US Code prohibits use of the CIA seal in a manner which implies that the CIA approved, endorsed, or authorized such use. If you have any questions about your intended use, you should consult with legal counsel. Further information on The World Factbook's use is described on the Contributors and Copyright Information page. As a courtesy, please cite The World Factbook when used.
Why doesn't The World Factbook include information on states, departments, provinces, the European Union, etc., in the country format?
The World Factbook provides national-level information on countries, territories, and dependencies, but not on subnational administrative units within a country or supranational entities like the European Union. A good encyclopedia should provide state/province-level information.
Is it possible to access older editions of The World Factbook to do comparative research and trend analysis?
