The Nuclear Proliferation International History Project recently announced a launch of the “new, improved” digital archive. The archive is maintained by the Wilson Center (as in Woodrow Wilson) in DC, a research hub for scholars of public policy. The archive primarily makes accessible documents for issues relating to the Cold War, North Korea, and Nuclear Proliferation.
“Constructed and maintained by the Wilson Center’s History and Public Policy Program, the Digital Archive contains newly declassified historical materials from archives around the world—much of it in translation and including diplomatic cables, high level correspondence, meeting minutes and more.”
The ‘documents’ available appear to be mostly second generation English text translations, with decent side-bar metadata on where to find the original source material (although some are PDF scans of original documents). While there is little visual or dynamic media, the information is rich and the interface easy to use. My knowledge of cold-war Budapest is practically non-existent so reading this telegram from 1956 was quite an eye-opener.
