Gina,
Thanks for taking the initiative to spearhead this initiative. I know The Professor had began a book club on GC back in 2002 but the ball was dropped.
How about just starting a new thread for each book you all read because you never know 2 years from now

someone might do some searching and find a thread on a book and bring it back to the top to reignite the flames of discussion.
I will be back later with ideas if I have any. I was MIA with company in town.
Also JUST A FRIENDLY SUGGESTION, vary your book topics -- fiction, non-fiction, etc.
