I've got a pretty comprehensive reference library, from the basics like Elements of Style, and various unabridged dictionaries (including the O.E.D. 20vol. compact edition), thesauri, books of quotations, the Encyclopedia Brittanica, and various references on the craft of writing. Also lots of religious texts, including everything from the ancient near East and Asia to the Book of Mormon and Scientology, copies of the Bible in various translations and versions, including in the original Greek and the Latin Vulgate, and Spanish, and various Bible Commentaries and the 12 volume Interpreter's Bible. References on history and philosophy, including the complete multi-volume Story of Civilization by Will and Ariel Durant. I've got references on metaphysics, magic, magick, mythology, Tarot, conjuring, and confidence games. And an extensive selection of books on history, military history, armaments, armor, firearms, and other weaponry from all time periods and locales. I also have some fiction, dictionaries, grammar and reference books in Latin, Greek, Spanish, French, Italian, and German.
