I saw these books in my parents' theocratic library and wondered if they should be there - I'm not sure about all the titles and names I just managed to scribble them down:
The Two Babylons (I do remember they had this one from back in the 70s)
The Works of Josephus
If God Spare my Life William Tyndale
The Jerusalem Bible
A Short History of the World
I wondered if anyone knows what the Society's take is on these books as I thought they should only have their literature, I'm sort of tempted to slip in book or two of my own and see if they notice
