I am impressed with how rapidly the Church has moved in the past couple of years to make more information readily available to its members and the public. Have you explored the new features on the LDS Gospel Library app and at LDS.org?
In the Church History section of the LDS Gospel Library, you will find the Gospel Topics Essays that take on some of the toughest or most controversial issues in Mormonism, the various accounts Joseph Smith gave of the First Vision, the new book, Daughters in My Kingdom about the history of the Relief Society, details on the lives and teachings of the prophets, some basic books and manuals related to Church history (including the Church History Study Guide for this year’s Gospel Doctrine course), and a valuable new resource written by authors whose names are listed, Revelations in Context, giving historical information related to each of the sections of the Doctrine and Covenants. This is a significant departure from standard manuals prepared by committees that allows individual historians to share their work. I presume that this may have a positive effect on the quality of the scholarship and writing.
A few examples include Jed Woodworth’s “The Messenger and the Manifesto” (pertaining to Official Declaration 1 ending polygamy) in Revelations in Context, the Gospel Topics essay, “Race and the Priesthood” (I’ll also mention the essay on the Book of Abraham since it’s relevant to some recent posts here), and the essay on the First Vision accounts of Joseph Smith, complete with links to the Joseph Smith Papers material where you can see the actual documents and read the transcript. A wealth of resources awaits you. Kudos to the many programmers, researchers, writers, editors, and others who have worked so hard to make all this possible.
