> The publishers of our ebooks require that the ebooks you “purchase” from Bookshop.org are only licensed to you. Even DRM-free books are subject to some restrictions and may not be owned outright. However, even in the case of an ebook being removed from Bookshop.org by the publisher, users who purchased the ebook previously will continue to have access to the ebook file. Depending on the circumstances, in the unlikely event an ebook is removed from your library because of a rights issue or otherwise, Bookshop.org will refund the purchase price you paid.
