Call of the Kami is still in #1 on my Goodreads list of books on or containing Shinto. I have added all the other books on it (or that had references to it in stories and poetry) that I know of.
I was actually surprised that there was not already a list for Shinto. This being such an overlooked religion was one of the factors that lead to me writing a poetry book to make some of the lore and outlook more accessible.
I would also like to see more people voting on that list for their favorite books on the topic (or adding ones that I don't know of).
