Beginning in 1974, Larson was a scripture translation researcher and guide writer for the LDS Church. He resigned in 1985 and left the LDS Church after he, through his research, lost faith in the Book of Mormon and other scriptural writings of Joseph Smith.[1]
After leaving the employment of the LDS Church, he worked as a religious archives specialist at the Marriott Library of the University of Utah. In 1988, he received a master's degree in library and information sciences from BYU. He later earned a PhD in theology from the University of Birmingham. In 2001, he became an associate librarian and curator of manuscripts at the Marriott Library. He retired from this position in 2011.
