The overall site design and layout is pretty good, although you might want to think about the placement of the Lilja's Library banner. To me, a banner near the top of the page like that says "CLICK ME!" which leads a visitor, and potential customer, away from your site. I'd think about maybe putting it under the under the books and before the feedback form. Then, if they don't see anything that appeals to them, they can click it (but not before).

Also, maybe try having the books on the main page show the lower priced books. I realize your customers are probably used to seeing higher prices than the rest of us, but if they see $800 right off the bat, they might think "wow, this is $$$." Just a thought.

In that same vein, you might want to have the default sorting for your books pages (eg, signed first edition) be "Price: Low To High" to avoid potential stick shock. That way, they can see exactly what is in their price range.

I think I might have one or two other ideas for you, but I have to go to programming class...
