good site.. may be you can add more of book.. if you have much books.. I think many people will give long time to stand at your site.. You have a good idea
you may submit your site to numerous search engine friendly web directories,it drives considerable amount of traffic..
I love the look of your website. The nice bright colous are not over powering and the site is not over crowded. Just get that traffic and get people to take a look, I'm sure it'll be really successful!
The site is good looking but some functions are not working like the very long google search box close and the page swirl on top left of the page.I viewed it in opera.It may be due to javascript error.
