It looks like BB has discovered one of my favorite sites: Fantastic Fiction. I go there when I'm trying to figure out what order to listen to my various audio books if they're in a series. I recently tracked down some police procedural mystery dates by Lawrence Block (most of his I've listened to are the Matthew Scudder protagonist, but he is prolific and has several interesting series.) And the Preston and Child "Pendergast" series, I came late to them but wanted to listen (or read, if the audio book wasn't easily available) in order.
