We call works 'public domain' if their intellectual property rights have expired, have been forfeited, or are inapplicable. As rights are country-based and vary (and in some places, non-existent), a work may be subject to rights in one country and be in the public domain in another.
To learn about the length of copyright in different countries, check this website. Some countries have different regulations for books that are already public domain in their original country. For more information, check this link. You can publish public domain books that are not yet public domain worldwide if you select the correct territories upon upload.
PublishDrive accepts public domain books, but some of our distributor partners don't take them. We don't take public domain books to Amazon. Some stores, like Google Play might accept them but remove them later.
If you try to publish a public domain book in a store where it is already available for free, they will most likely refuse it (as most stores can’t have duplicate content). You have more chance of seeing it on the shelves if it is a unique translation, or contains annotations, notes or unique illustrations.
We recommend that you publish unique content with exclusive copyrights.
