Public domain books and other writings - what can you do with them? When a book (or any written work) enters the public domain, you can copy and use it without getting permission or paying fees. That’s because public domain books are no longer — or never were — protected by copyright. What can you do with public domain books? Republish them as they are, or add your own material to create new works.
