If these books have come out and are in the market,
you should have a specific link to the store pointing
to your books. Like for example, Barnes & Nobel or Border
or another chain like that.

If you are selling them through Amazon, then you should
directly be pointing to these books of yours.

Any one reading your pages would expect to see these links
or a shopping cart or paypal or credit card if you decide to sell
them on your own.

Or maybe you can start a chapter a week of all the books
you have for free.

What I mean is there is no business plan showing on these pages
what you wanna do with them.

Or maybe I am missing the whole point you may be making.

Other than that, I think you have a super website.
