The Pearl of Great Price
A Selection from the Revelations, Translations, and Narrations of Joseph Smith First Prophet, Seer, and Revelator to The Church of Jesus Christ of Latter-day Saints
The Pearl of Great Price is part of the canonical standard works of The Church of Jesus Christ of Latter-day Saints (LDS Church) and some other Mormon denominations.
The first paragraph of the Introductory Note in the LDS edition of the Pearl of Great Price states: "The Pearl of Great Price is a selection of choice materials touching many significant aspects of the faith and doctrine of The Church of Jesus Christ of Latter-day Saints. These items were produced by Joseph Smith Jr. and were published in the Church periodicals of his day."
The name of the book is derived from the Parable of the Pearl told by Jesus in Matthew chapter 13.
