I have a growing collection of publications like Scientific American, Ladies Home Journal, and other magazines that are still in print today. Plus old books for publishers that no longer exist. They are all from prior to 1920. I'd like to digitize them so they are freely available to view online, and so people can search through them.
Is there anything legally that would prevent me from doing this? I have read through this question and it sounds like the answer will be 'yes, it's not allowed'. Furthermore, does that fact that a magazine is no longer in print (McCalls magazine for example) have any bearing on the copyright?
