I need references for books on the history of spiritualism, theosophy, the Golden Dawn, etc. Not modern New Age books on their ideas, but scholarly works on what those movements were doing in Great Britain in the nineteenth century, up to (you guessed it) 1884. Overview-type references would be a good place to start, though I’d also be interested in books that really delve into the nitty-gritty, so if I decide to make use of particular people or events I’ll be able to do it properly.
Any other occult movements of the period that I haven’t mentioned here are also welcome. This is a topic that especially needs sorting of wheat from chaff, so if this is a subject you know, please do point me at the reliable books.
