title_body: Can I copy or publish, text from a website. Can I copy or publish text&mdash;from a website&mdash;that is in the public domain?
  
  The text was already published as hard cover, in many apps, and as PDF. But never for Kindle (AZW3).
upvoted_answer: I am not a lawyer, but: If the text is in the public domain, then yes, you can use it. Be sure that it really is in the public domain, though—copyright lasts for a very long time. Also bear in mind that if the text is annotated, translated, or altered in any other way, or if it's a collection of public domain works, there may be further complications. If you have any doubts, you'd be best advised to contact an IP/Copyright lawyer.
