Thank you for this. In the meantime, I went browsing on Amazon and found 'The Oxford Guide to Arthurian Literature and Legend' (Alan Lupack) and also 'The Arthurian Handbook' (Norris J Lacy et al). Both seem to do what I'm after, so I am starting with the former. I will bother sarcasticchick when I have specific questions! Thanks again, and looking forward to more of your reviews.
