The PURSUE Release 01 catalog identifies 59_64634_711.5612[7-2852 as Department of State material with no incident location and an incident date of July 18, 1952.1 Its description says the intended record is a two-page memorandum about increased UFO reports, possible explanations for the increase, historical UFO records, and U.S. Air Force opinions on UFOs.1
The PDF link attached to the row does not match that description. The hosted asset is a six-page July 18, 1963 memorandum from the Executive Office of the President's National Aeronautics and Space Council to Robert F. Packard in the State Department's Office of International Scientific Affairs, under the subject Thoughts on the Space Alien Race Question.2
That linked scan appears to duplicate the neighboring 59_214434_SP 16 [7.18.1963] release item rather than the 1952 memorandum described in this record.12 The page should therefore be treated as a catalog-link conflict: the release metadata preserves a 1952 State Department UFO-memo title and description, while the public PDF currently opens a 1963 space-policy memo about alien intelligence.
The record matters as a release-integrity warning. Researchers should cite the row title and 1952 description only as catalog metadata unless the Department of War supplies the missing two-page memorandum or corrects the asset link.12
