Opinion is still divided with no middle ground: Magaret Murray's works on witchcraft are (1) good or (2) wild speculation.
The website of the Folklore Society (London) isn't working well today. About two weeks ago I saw there the title of an article which I think was in an issue of 'Folklore', c 1995, entitled:
Margaret Murray: Who Believed Her, and Why?". I'd like to see that someday.
