The top fifty SF & fantasy books (where from? I don't know). Bold the ones you've read, strike the ones you hated, italicize the ones you couldn't get through. Asterisks for the ones you loved - more asterisks, more love. Plus signs for the ones you own. Pellegrina's added rule: question mark if you can't remember if you read/own it...
