Now you can easily offer e-book editions of your titles to the growing eBook market. Once Selfpublishingus.com designs your book files, and after you have approved your proof from the printer, we can convert it into an ePub file. Upon approval of that file (which you may view on any e-reader or through a software program), we will provide you with an e-book file that can be uploaded to an online store. Note: Amazon is now accepting ePub files for their Kindle e-reader so it is no longer necessary to have two "e-files".
