Site: "On October 4, 1957, the Soviet Union successfully launched Sputnik-1, the world's first artificial satellite. Only about the size of a beach ball (22.8 inches or 58 cm. in diameter) and weighing 183.9 pounds (83.6 kg), it orbited the Earth in around 98 minutes.
"The Sputnik launch marked the start of the space age and the US-USSR space race, and led to the creation of the National Aeronautics and Space Administration (NASA).
"This guide is intended to help direct the researcher to information on Sputnik and the space race as well as artificial satellites. in addition to suggested books on the topic, links to digitized primary resources and other online resources for information on the history of Sputnik are included.
Site: "This guide was originally compiled in 2007 on the anniversary of the Sputnik launch (1957), but has been updated with additional content."

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."
