Just finished a book and would like more in the same vein? Here's a new toy to play with. Just type a title into The Book Seer (developed by Aptstudio), and voila! a list of reading recommendations comes up for you.
The suggestions I think are based on buying patterns on Amazon.com, and there is a second list of recommendations from LibraryThing which is based on the books that people actually have in their libraries.
(Thanks Chet for the lead ...)
