After Joseph Smith's death, Emma Smith kept the marked Bible and manuscripts of Joseph's New Translation of the Bible. These eventually became the property of the Reorganized Church of Jesus Christ of Latter Day Saints. Because of random marks made on the pages of this collection, scholars have questioned whether or not any markings were added after Joseph Smith's death. The authors examine the notations made in the printed Bible Joseph used during his translation, and they conclude from the evidence that the manuscripts were not significantly changed after his martyrdom. They also point out that Joseph had finished translating and was editing to polish the manuscripts for publication.
