History Day Blueprint

Site: "The CIA releases millions of pages of documents each year and frequently releases items of public interest on this website. The Library contains a wealth of information, from unclassified current publications to basic references, reports and maps."

Site: "After decades of unsuccessful attempts to gain access, the public is now finally able to review the President’s Daily Briefs (PDBs) from the Kennedy through Ford administrations. The collection was released in 2015 and 2016 and sheds lights on the intelligence and analysis the presidents received at the time. They are posted on the Central Intelligence Agency (CIA) website and are available to anyone to read.
No briefing has been released in its entirety. During the declassification review, portions that were deemed too sensitive to release were redacted. In some cases, entire entries are missing while in others just parts are. I recently explored these briefings and released an Electronic Briefing Book where I share my impressions of the briefings and provide additional historical context."

Site: "This compilation from the 1950s is combined with documents from a FOIA case on the Sputnik program - never before on the CIA.gov webpage - that contains additional memoranda and information reports through the early 1960s. This collection comprises 59 documents and 440 pages with insight on CIA intelligence and analysis of Sputnik-1, -2, and -3, as well as the Soviet ballistic missile program from 1955 to the early 1960s. Over half of this release provides new information on the early Soviet space and missile programs."
