“This is an important database for researchers and students of 20th-century international relations, British history, and Cold War operations. Both experienced scholars and casual browsers will appreciate the intuitive interface and numerous search options. Quality organization and enhanced features add to the archive’s value and usability. In sum, this is a significant resource of British intelligence and security policy information and an excellent companion database for libraries that already own or subscribe to Gale’s U.S. Declassified Documents Online.”

“A must for scholars of British history, the Cold War, and 20th-century international relations, this work from Gale makes available 500,000 pages of previously classified information on the British Empire. Materials come from the UK Ministry of Defence, MI5, the Cabinet Office, and more, and collectively offer a rich and detailed history, spanning 1905 to 2002. Impeccable organization and robust search functions only add to the resource’s utility.”
