List some of your favorite books (classics or popular are welcomed) and then others can join in and recommend books they have read that they think you might like...
I'll start with some old time faves:
Franny & Zooey
The Elegance of The Hedgehog
A Tree Grows in Brooklyn
Harry Potter series
Daddy Long Legs
I'm sure there are many more efficient sites for this, like amazon and goodreads, but a lot of PerC people have good taste :)
