I imagine that there are a host of books on the undead, but I will put on this page those that particularly catch my interest. Some covers link to Amazon.
Zombiemania: 80 Movies to Die For
A great, extensively researched movie guide. See the Cult TV and Film section of their Web site.
Monster Island
Wellington writes a great book with some interesting new ideas, yet still adheres to the genre. Well worth a read. I plan to read the sequel, and the third book as well.
World War Z: An Oral History of the Zombie War
World War Z has the obsessive detail and seemingly boundless imagination of Max Brooks's Survival Guide, but also has the heart and soul that the Survival Guide lacked. Read it.
Cell
This isn't one of Stephen King's better efforts, but it's OK, and if you've always wanted to see what Stephen King does with zombies, here's your chance.
The Stupidest Angel: A Heartwarming Tale of Christmas Terror
I laughed all the way through this book by Christopher Moore, sometimes until I cried. Zombies on Christmas. Who would have thunk it?
Goon: Nothin' but Misery
Written by Eric Powell. This great comic series features a huge thug who just can't stand zombies. Powell has written two other books in the series, but I haven't read those yet.
The Serpent and the Rainbow
Written by Wade Davis. A pretty cool movie starring Bill Pullman was based on this book. The book is less flashy, but just as interesting. Find out what the "zombie cucumber" is.
The Walking Dead
Written by Robert Kirkman and Tony Moore. A comic book series set in a world overrun with zombies. The first six issues have been collected in this volume.
The Magic Island
Written by William Buehler Seabrook. An interesting account of this man's travels in Haiti, it first introduced zombies to mainstream western culture.
The Zombie Survival Guide: Complete Protection from the Living Dead
Written by Max Brooks, Mel Brooks son. It's good to know that being the child of a celebrity doesn't prevent this man from dealing with real issues.
The Book of the Dead
A collection of short stories set in Romero's universe. I'm only halfway through, and I already recommend it. There's also a Book of the Dead 2.
Zombeena
Mirry Rose brings you a horror/romance comic about a young man and his unfortunate love life.
