Items of interest are generally available for low prices - barring currency exchange rates and shipping costs.
Here are a couple of recent items I managed to score:
Clive Leatherdale's Dracula: The Novel & the Legend: A Study of Bram Stoker's Gothic Masterpiece (The Leisure Circle, 1985) arrived on August 5th.
I'm not big on Dracula scholarship, but Leatherdale has some interesting things to say on the development of the Vampire Myth.
Jan L. Perkowski's Vampires of the Slavs (Cambridge, Mass.: Slavica Publishers, Inc., 1976) arrived today.
This is the paperback version. I've previously borrowed a hardback copy - but, in hindsight, that may have been a library hardback edition.
Certainly one of the most influential vampire anthologies, it's also not cheap to come by: some copies can sell up to $295 onwards. I was lucky enough to win this one for significantly less.
