This was helpful with certain folklore and vampire portrayal references for some research I'm doing, but there were many inaccuracies that boggled my mind (such as geological/cultural) and an odd mixture of superficial and submersive research. And, yes, this was published in 1994, but there was way too much focus on vampire-related fan clubs (yes, I'm aware this was likely to help fans back during the days when the Internet couldn't give someone access to every niche fan club on the planet) and many of the cultural sections were obviously written through the screen of an old straight man who's just some vampire enthusiast (the section on homosexual vampires is scant and indifferent yet there are 4 pages dedicated to lesbian vampires, as well as an entire section of Women Vampires yet not one on Male Vampires, as if female vampires are a different entity who just exist to seduce men and kill children).
