I define "wBook" as a book made available on the
World Wide Web (a.k.a. Internet). Unlike eBooks or iBooks.
wBooks are NOT encrypted, nor stored in hidden folders. And
special eBook readers or iPhones or iPads are not required to
read wBooks. Instead, wBooks should be written in HTML (Hyper
Text Markup Language), the language interpreted by all
browsers. So anyone can read then, on any computer
(running any OS) or on any smart phone, or
smart device that has a browser.
A wBook should be written in one HTML page. However,
if converted to PDF format, so that it can be printed in
8"x11" pages, it can be just a few pages, or a lot of pages.
The wBooks bellow are really short. For example, "The Life
Force" book, in PDF format is only 16 pages.
To read these wBooks, select one of the following covers:

Because they are in HTML format, you should be
able to change the size and color of the letters, and background
color.
And unlike printed books, wBooks can contain
animations, sounds, and videos. And we can also create an
audio version of it (in mp3 or wave format).
Since they are so easy to enhance, or make
changes to it, I have now decided that it would be best to use
Revision numbers, or Version numbers instead of
Editions.
