You've written a wonderful book and would like to sell it. A long list to take care of which makes people shy away. But still, the book has to be printed at your expense. This is called an e-book.

No printing, no packaging, no shipping. The book is delivered encrypted to your customer's computer. Only your customer can open it with a unique user's name and password. Target marketing for your book via the major search engines. It will not get lost within a catalogue.
