The CIA Library, available to Central Intelligence Agency personnel only, contains approximately 125,000 books and subscribes to about 1,700 periodicals. The Library maintains three collections—Reference, Circulating, and Historical Intelligence. The CIA Library regularly provides current critical information to the President of the United States and senior government officials. Some CIA Library personnel work in one of several offices that directly support analysis, intelligence collection, and other business areas. These individuals analyze, develop and deploy innovative information/software systems and capabilities to enhance the CIA's capabilities to collect, produce and disseminate intelligence.
