Another thing I might add is that (I believe) each of Lady Mimi's recommendations contain a bibliography that adds helpful additional books you can read for more information. I can add my own recommendation of Don Kraig's "Modern Magick" which has a super bibliography for those who are particularly interested in ritual magick. For things Wiccan I can also recommend the Farrars and Cunningham's books. He also wrote an excellent book on the magical uses of oils, powders, and brews. If you check out each new book for their bibliography you will start a possibly endless path of discovery. Lady Mimi's shop can provide most of these (along with many helpful hints and suggestions as you have already found out).
