The extensive bibliography in the back is also worth having for one's own research. The articles are written by a group of all-stars in the field: Fischer, O'Conner, Widerker, Dennett, Zagzebski, Mele, Double, Pereboom, Ginet, and on and on (sorry to all those I've left out). With all the work being done on this topic, I wouldn't be surprised if Oxford will need to publish another edition with new articles in about 5-10 years. But for now, this is a great selection of essays and I highly recommend this for becoming familiar with the territory, even if it costs a wallet-killing 80 bucks!
