Most of the time, when I use a resource in a post I add the ‘Resources’ category to it, but some sources (books, podcasts, what-have-you) are so useful or thought-provoking that I keep coming back to them, and I feel they deserve a page of their own.

I have a huge backlog of books, so this is by no means a complete list of everything I have that I find invaluable, and I will continue to add to it as I read.
I also enjoy reading novels, and there are often resonant themes in the most unlikely of places.
Bates, Brian; The Way Of Wyrd: Tales of an Anglo-Saxon Sorcerer
Pratchett, Sir Terry; Johnny and the Dead
Pratchett, Sir Terry: The Discworld series is brilliant, although the books featuring the witches are of particular interest: Equal Rites, Wyrd Sisters, Witches Abroad, Lords and Ladies, Maskerade, Carpe Jugulum, The Wee Free Men, A Hat Full of Sky, Wintersmith, I Shall Wear Midnight
Gaiman, Neil; American Gods
Gaiman, Neil; Sandman (vols. 1-11)
