Lulu, the digital publishing platform, has expanded to include ePub formatted ebooks as a publishing option. You can choose to create your own ePub book or have Lulu’s Conversion Services do it for you. Your book can then be sold through Lulu and sent on to other booksellers – including the iBookstore.
