95 years if the copyright was renewed. But if a book was published before 1964 and the copyright was not renewed, it only remained in copyright for 26 years. I suspect this book wasn't renewed. Mortensen for some reason is huge right now. Even his International Photography magazine plates are getting bucks. I think he did a lot of junk, personally. But his fights with Ansel Adams in Camera Craft are fun to read. -----Original Message----- From: Peter Badcock <peter.badcock@xxxxxxxxx> To: pure-silver <pure-silver@xxxxxxxxxxxxx> Sent: Thu, Jul 25, 2013 7:14 pm Subject: [pure-silver] Re: Mortensen's The Command to Look: A Formula for Picture Success Does anybody know how long a book's copyright lasts for if it was first asserted in 1937 and the 6th printing made in 1948 ? I note these books sell for between $300-$700 on Amazon right now. http://www.amazon.com/The-command-look-formula-picture/dp/B000893L7W Regards Peter On 25 July 2013 04:11, Eric Nelson <emanmb@xxxxxxxxx> wrote: Here is the link to Mortensen's The Command to Look: A Formula for Picture Success http://share.cx.com/HYqdzt Enjoy. e
