California Digital Library: “The U.S. Declassified Documents can now be cross-searched with the other archive resources on the Artemis platform.  You can filter search results by document type, classification level, publication year and by other categories.  Results can be analysed using the built-in Term Frequency and Term Clusters tools. U.S. Declassified Documents Online provides access to a broad range of previously classified federal records spanning the twentieth and twenty first centuries. The collection brings together the most sensitive documents from all the presidential libraries and numerous executive agencies in a single, easily searchable database. The search and discovery interface for the collection allows researchers to locate the full text of documents and quickly filter their search results by document type, issue date, source institution, classification level, and date declassified as well as other document characteristics. The collection is the most comprehensive compilation of declassified documents from the executive branch. The types of materials include intelligence studies, policy papers, diplomatic correspondence, cabinet meeting minutes, briefing materials, and domestic surveillance and military reports. The collection editors have actively monitored the release of formerly classified documents from presidential libraries. They have also added numerous major releases of declassified documents from the Atomic Energy Commission, Central Intelligence Agency, Department of Defense, Department of Justice, Department of State, Federal Bureau of Investigation, National Security Council, White House, and other executive agencies. Because the majority of the documents are presidential records and all of them were formerly classified, these records provide a unique, behind-the-scenes view of the highest level of American policymaking on the most sensitive issues of national security and foreign policy.”
