We need local book clubs like this, so many of them that there's one for any book you might be reading, or the well-preserved records of the last time there was an exhaustive group discussion on a particular book.
I'm thinking of lists and databases or big file cabinets and digital printouts speeding by with every conceivable date and day of the week. "We discussed 'Tarzan of the Apes' in 1915 and I remember it as a very good group."
