What is the advantage of publishing an ebook version of a book?
The biggest advantage to publishing ebooks is one you never usually hear – that ebooks can be delivered instantly. When people are looking for specific information, getting it instantly is often a strong selling point. Ebooks also offer a low-cost way to put a book into the market. Aside from creating the file, which you can do for free here, ebooks cost an author nothing. That means profit margins are high.
