Easy and Risk-free The software that I am about to introduce you to, is a powerful professional quality tool, that makes it simple for anybody to get started in Information Publishing.
If you can create web pages - then you can create and publish E-Books.
(and even if you can't, most modern word processors include a "Save As HTML" feature).
Simply create a set HTML files containing the information you want to sell, and then run Activ E-Book Compiler - and you'll have a self-contained Windows Program (".EXE") which users can download and run, to view your E-Book. You can even restrict access to parts of your E-Book with passwords, include links to relevant web sites, or sell advertising space in your E-Book.
