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.

PublishDrive accepts public domain books, although not all of our distributor partners will make them available in their stores. Some stores might accept them but remove them later.
Many public domain books are available free on the internet. If you try to publish a public domain book in a store where it is already available for free, they will automatically 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. You can expect the big stores (Amazon for instance) to be more vigilant regarding duplicate content than the smaller ones. Read here about Amazon's requirements.
We recommend that you publish unique content with exclusive copyrights.
