Many of our titles are available in e-book format (as well as some - like short stories - that are ONLY available in e-book form). To make things easy we have made the books available directly from most of your normal e-book vendors, Amazon, Barnes & Noble, Sony, Kobo, Apple etc - and if you can't find what you want there - then simply go to www.smashwords.com and download the appropriate version there.
Happy e-reading!
