In September 2015, photographs of one of Joseph Smith’s seer stones were published in the Joseph Smith Papers: Revelations and Translations: Volume 3.To go along with this, an article was published in the October 2015 Ensign  that gave a brief overview of seers, seer stones, and the translation of the Book of Mormon, and also included one of the photographs. This was significant because prior to that, it had been unseen, locked away in the First Presidency’s vault. As it turns out, there were many that were unaware that a seer stone had been used in the translation of the Book of Mormon, and for some this caused some surprise and confusion.
This book goes much further than the Ensign article to “provide a friendly introduction to seer stones,” as well as to “provid[e] an introduction to the historical sources in an accessible style for Latter-day Saints and others.”  In doing so, they include sources both friendly and unfriendly to the church (but unfortunately do not always differentiate between them for readers that may not be familiar with some of them). This is an important book in that it is the first fully devoted to the topic.
The introduction talks about “Mormon Paradigm Shifts.” This is for those that were taken by surprise to find out about seer stones, in spite of a multitude of references in church literature throughout the years. “WIth so many Latter-day Saint scholars acknowledging and studying Joseph Smith’s use of seer stones, it is clear the the Church has not been hiding this information. And yet, as with many historically specific topics, without direct references provided in Church teaching materials and curriculum, the average Latter-day Saint would not necessarily encounter the seer stones in the course of their devotional study. …That is why the latest appearance of the topic in the October 2015 Ensign (and Liahona) was so important: it underscores how, even while keeping a sacred relic private, the Church continues to be open about the miraculous process of the translation of the Book of Mormon.”  [Read more…] about Book Review: Joseph Smith’s Seer Stones
