Overview

Digital National Security Archive unlocks a vast trove of important declassified U.S. government documents, providing vital primary source material to advance research in twentieth and twenty-first century history, politics, and international relations.

Working in collaboration with the National Security Archive to preserve and widen access to this significant material, ProQuest has created a far-reaching, curated collection of U.S. official documents. More than 650,000 pages are included, with many gathered through extensive use of the U.S. Freedom of Information Act by The Archive.

The digitized documents are made available in over 40 topic-based collections, with two new collections added each year. The curation of each collection is overseen by subject-area scholars to ensure the material provides the most discerning coverage of the topic.
