I have checked out a number of sites that will convert the pdf files into flip books but I am not prepared to pay the amounts that they are asking.
I use the pay version on http://www.pageflip.hu/ and it works really well. I did have problems with the load times on the free version but these appear to be solved in the updated script..
If you're java developer you may check this post http://www.sitepoint.com/examples/jquery/animate4.php
If you just need a flip book for website, you may use this online converter http://www.axmag.com/submit.html and embed the converted flash in website.
