Textual Critisim is a scholary analysis and attempt to recreate the original text. Even relativley modern manuscripts like Joseph Smith's English translation of the Book of Mormon can go through changes. For instance the Book of Mormon had Joseph Smith's manuscript, the printer's manuscript and then multiple editions. Each of these offered a chance for accidental and deliberate changes to the text.

B.566 Bushman, Richard L. "The Book of Mormon in Early Mormon History." In New Views of Mormon History: A Collection of Essays in Honor of Leonard J. Arrington, edited by Davis Bitton and Maureen Ursenbach Beecher, 3-18. Salt Lake City: University of Utah Press, 1987. Many scholars have concluded that magic "lay at the heart of nineteenth-century Mormonism," but they overlook the role that the Book of Mormon played in the attitudes of the early Church. Bushman proposes to analyze broad themes in the Book of Mormon and consider how they affected the early Church. Also explains how prominent the theme of record keeping is in the Book of Mormon, and the manner in which whole societies lived, perished, and were restored based on record keeping. The importance of records and their translation greatly affected the Church, especially Joseph Smith who was constantly occupied with translating records. [B.D.]
