Many thanks to SWLing Post contributor, Alexander (DL4NO), who writes:
I just found a German reference to the CIA Freedom of Information Act Reading room
https://www.cia.gov/library/readingroom/
As a first test I searched for “radio design”. A few of the documents found:
- ACTIVITIES OF AMATEUR RADIO DESIGNERS
- JPRS ID: 8744 TRANSLATION ELECTROMAGNETIC SHIELDING DESIGN FOR RADIO-ELECTRONIC EQUIPMENT
- DOSO INSTRUCTION FOR AMATEUR RADIO OPERATORS; BULGARIAN RADIO EQUIPMENT PRODUCTION
- AIRCRAFT RADIO COMMUNICATIONS IN THE USSR
This could be an amazing source, especially of historical information from the Eastern Block. But expect any search to be real work: Only the title and some classification of the documents are searchable. The rest is scanned documents.
Very cool–thanks for sharing, Alexander. I spent a little time this morning browsing the results using various radio-related search strings. It is a very deep archive.
