Well since you want to know many different things, here are some suggestions.
There's some on wicca and paganism in here, although I suggest if you want a variety of things to simply just get some history books, and books on the things you want to know.
Say if you want to learn more on herbs, you Don't need to have a ''magick book'' for that. A simple herb book will be fine!
I am new here by the way, can you maybe give me some tips on this site?
