There are others in boxes, in the back rows of bookshelves (we have books two deep on some shelves), and in the garage -- including a Russian Synodal translation, a Greek New Testament with parallel commentary in Modern Greek, the translation by Monsignor Knox, a New World Translation, and a fair number of Gideon New Testaments that were given to me at school or by relatives.
I also have several collections of non-canonical Christian and/or Gnostic scriptures, a Jewish Tanakh, a Qur'an, two translations of the Bhagavad Gita, two translations of the Dhammapada, six or seven translations of the Dao De Jing, two copies of the Book of Mormon, Buckland's Complete Book of Witchcraft, Mooney's History, Myths and Sacred Formulas of the Cherokees, the Analects of Confucius, a number of books of Norse, Greek, and Irish mythology, a book of Reform Jewish responsa, an edition of the canons of the Orthodox Church, and a fairly decent collection of Orthodox, Catholic, and Protestant prayer books, missals, and service books in English, Greek, Slavonic, Latin, and German.
