That is so exciting that JCF is putting together The Way of the Animal Powers.
From what I recall, The Way of the Animal Powers was also available as Vol. 1 in The Atlas of World Mythology volume series. I did not see on your photo here of the cover a “Vol. 1.”
The other book you are looking for, The Language of the Goddess by Gimbutas, is now available on Amazon and in several other online bookstores, as well as some of her other books on goddesses and goddess culture. I hope you can find the download in the server, Stephen–I missed that one!
