(Via Pharyngula, Respectful Insolence, Evolving Thoughts, A Blog Around the Clock, etc.)

UPDATE: And Stranger Fruit, Good Math, Bad Math, and Afarensis...

Looks like Mark Chu-Carroll at Good Math, Bad Math has gone to the most trouble of annotating his list, as well as having read more of these books than anyone else.
