More Chicken Soup

If you own a copy of Richard Greene and K. Silem Mohammad's philosophical anthology, The Undead and Philosophy: Chicken Soup for the Soulless (2006), then you might be wondering about the content of Zombies, Vampires, and Philosophy (2010).

After all, the same editors are involved and it's also going to be published by Open Court.

The question is, how much does it differ from the previous publication?

Is it a whole new anthology, or merely a rehashed, retitled reprint of the first book?

Here's what Open Court's description of the book has to say on the matter:

This is an expanded and re-titled edition of Open Court’s The Undead and Philosophy: Chicken Soup for the Soulless. It includes two new chapters and a new introduction.
