You can get those Itoya books from:

www.misterart.com
www.dickblick.com

And on ebay from user "hofgroup.com" (I guess 
you can go to that site too, though I think 
they're cheaper on ebay).  An 11x14 book will 
run from $10-12 or so plus shipping. :)  I've 
bought from all of them and would use any of 
them again.
