As the author of a hardover published book entitled "The Doctor Who
Cures Cancer", I'd like to shed some light on Books versus eBooks.
While it's certainly true that maybe 99% of of the eBooks out there
would never find a home with a publisher, there is a booming market
for eBooks for niche markets.

Ebook authors try to focus on a particular subject with a narrow, but
highly interested, audience. In contrast, regular books often, but not
always, try to appeal to a mass audience. (With regular publishers a
book with a narrow audience might be of very little interest to the
publishing house.)

There are eBooks on all sorts of topics, from health to various
software programs, and there are even eBooks on how to publish and
sell eBooks.

I've purchased two eBooks and was satisfied with both. If I hadn't
been satisfied, I had 30 to 90 days to get an automatic refund. So
there was little risk.

There are health eBooks on how to rid yourself of bad breath, acne,
asthma, etc.
They are often remedies that are of interest to a specific market,
even if they would be of little interest to book publishers.

There are several advantages to eBook publishing. The first is that
the author doesn't have to wait 18 months to see his work arrive on
the shelves.

The second is that the author doesn't have to rely on the honesty of
the publishing house in order to get paid for his work. (This is no
small problem.)

By going the eBook route, the author is cutting out the middle man. So
authors have a chance to get paid what their work is worth. And they
can write on a topic that might have only 5,000 buyers and still make
a decent living, especially if they are able to write several eBooks.

I now have an eBook entitled "It's Not Just For Sex" with a website by
the same name. It's targeted towards people with erectile dysfunction
and/or high blood pressure. My hardcover book probably wouldn't make a
suitable eBook, because eBooks are most often "How To" books.

I would recommend writing eBooks as a profession to anyone who has an
expertise on a marketable topic. It could be "How to grow georgeous
irises in 15 minutes a day," for instance. With the power of Google
Adwords, you can reach your niche market for very little money.
 

You could order the book and cancel it if you aren't satisfied. If you
are satisfied, then your integrity would not allow you to ask for a
refund.
