The American Library Association has put together a wonderful resource guide for book discussion groups. Included in their information are generic questions your group can use with any book to get the conversation rolling. They also provide a review of sources of questions for specific books. Other great sites include: LitLovers.com and Reading Group Guides
An easy way to find discussion questions for a specific title is to Google the title along with such phrases as book discussion questions or book group questions. You'll be pleasantly surprised with the results!
