A reader over at Too Much Horror Fiction is looking for this one:

I am trying to identify one in particular published in the early-mid 1970s. It featured cover art with bright orange and yellow flame and background hues, with illustrations of skeletal and spirit figures with a castle. The collection was really presented as a genre study of sorts, and was very well organized around the nature of the supernatural threat: psychological threat, physical threat, etc. The collection was broad but included many classics in gothic, Victorian and early 20th century fiction.

Can anyone figure this one out?

Edit: The book has been identified. It is Ghosts, Castles and Victims Tales of Gothic Horror edited by Jack C. Wolf and Barbara H. Wolf.
