The Penguin Book of the Undead: Fifteen Hundred Years of Supernatural Encounters, by Scott G. Bruce.
Just got this downloaded, really looking forward to it. Came across this at Medievalists, in a short article about how Medieval people dealt with those pesky dead people who refused to stay dead and buried. The cover art, which I think is fabulous, is by Anton Semenov, check out more of their work here.
This will make lovely nighttime reading.
