I found this book in the library when looking for information on the 1931 film Dracula, and was rewarded with all the material I wanted. The bulk of the book is about portrayals of Dracula on stage, screen, and in literature; although there are a couple of early chapters on the historical fact behind the legends they add little to what is generally known about Vlad the impaler, and make no attempt to trace vampire legends any earlier. Although one of the chapters is titled "The Ancestors of Dracula", this chapter is about literary ancestors of Bram Stoker's character. The main limitation to this book is that its publication date precedes much of the more recent interest in vampires, probably spawned by the success of Anne Rice's Interview with the Vampire. No mention is made of vampiric representations or appearances in the visual arts or music--an updating of the book might well cover the several versions of Dracula that have been done as operas or ballet. But as a reference to various media presentations of the Count up to 1975, this is fairly good.
