The "Book Of Enoch" was part of the Bible up until the year 400 AD, at which time a conclave of Bishops met to decide, amoung other things, whether to include Enoch or Revelation in the Bible. They chose in favour of Revelation, and thereafter Enoch was omitted.
I have read The Book of Enoch, The Book Of Jubilees, and the Book Of Secrets Of Enoch, and have copies of the first two, and photocopies of parts of The Book Of Secrets Of Enoch.
