As far I can see you only have two books from Dr. Rudolf Steiner in your mega. You put them in the Theosophy folder as well which is kind of misleading. How about a Anthroposophy folder?
I could provide some books for it.
I l add a pdf I found on my hard drive that connects some to the dots of the history of occult societies in Europe quite well. I haven´t read the whole text nor do I agree with all what is written there but please don´t put Dr. Steiner and in the Theosophy folder…
A good introduction would be his autobiography "The Story of my Life".
