The original 46 page memorandum text and associated figures is a scientific work. It was originally authored by Alan Turing as a civil servant of the National Physical Laboratory. It was published before August 1989, and it was created before June 1957. Even for literary works, the copyright expires 50 years after the creation. The file, as a photograph, may be under Crown copyright. There's a lot of information
Wikipedia has a template for public domain {{PD-BritishGov}}, but that copyright status doesn't exist on Wikisource. The status of the copyright of this work will need further research by someone with more experience with Crown copyright. --Ashawley (talk) 03:46, 1 February 2022 (UTC)
- Turns out there was a license template for {{PD-UKGov}} on English Wikisource, which is the copyright status that applies here. --Ashawley (talk) 13:52, 14 February 2022 (UTC)
Scan quality edit
The OCR is having trouble with the scanned images in the PDF. Maybe it would be better to hold off on transcription and find a better scan. --Ashawley (talk) 04:21, 1 February 2022 (UTC)
