[manton] cleverdevil Just did a little research on this because I was curious. Sounds like if the 1946 book's copyright had been renewed after the initial 28 years, it would be automatically extended and still under copyright today. But if it hadn't been renewed, it should be in the public domain now. (In theory you can search the copyright office, but not seeing how without contacting them.)
