That reminded me, when i was in junior high i started collectin dragon magazine, this one was the second issue i ever bought:
I still have it and it is still my favorite issue. it has tons of creatures in it, and some great undead stories. There is an article called "the ungratefull dead" which deals with various types of undead (zombies, ghouls, skeletons), and has a story or short essay on the history of the creature, or a story that refences them :D
