The New Revised Standard Version is an authorized revision of the Revised Standard Version of 1952, itself a revision of the 1611 King James Version. Since the publication of the RSV, significant advances had been made in the discovery and interpretation of the Bible documents. The Dead Sea texts of Isaiah and Habbakuk, together with other early copies of the Old Testaments books from the same area also presented new translation challenges. In order to take these discoveries into account, along with recent Semitic language advances, the New Revised Standard Version preparation began in 1974. This edition contains the Apocrypha, or Deuterocanonical Books in a convenient text format with translation footnotes.
