Blood is the Life: Vampires in Literature edited by Leonard G. Heldreth and Mary Pharr

This collection of essays analyzes the role of vampires in literature. It's particularly interested in both Dracula and in the changes in the portrayal of vampires at the end of the twentieth century. The collection of essays covers a fairly broad span of literature. The essays contribute more to an understanding of the individual works they focus on than to overarching theoretical developments.
