Query: Excellent well-researched work on astral lycanthropy ...

This is a very well-documented book on astral lycanthropy and vampyrsm. The listing and definitions of the many words for "vampyre" become a bit tedious but it's all worth the read. The book addresses the subject in terms of shamanic work. If you're interested in magick, pagan religion, shamanism, etc., or if you are a practicing mage get this.
