This ebook contains articles from BYU Studies on a variety of topics related to the Doctrine and Covenants. Christopher C. Jones recounts research that has allowed us to identify the person addressed in D&C 39 (James Covel, not James Covill) and again referred to in section 40. Learning that Covel was a Methodist minister, not a Baptist, enabled Jones to learn a great deal about this formerly unknown person. John W. Welch and Trevor Packer examine a newly found manuscript of D&C 65; Steven C. Harper discusses Lazarus, the rich man, and D&C 104:18; David J. Whitaker explains the use of pseudonyms in earlier editions of the D&C; Dean C. Jessee and John W. Welch examine Joseph Smith's letter from Liberty Jail, March 20, 1839; Ronald E. Bartholomew details the textual changes that occurred in the development of D&C 130:22; and George S. Tate considers the vision received by Joseph F. Smith (now D&C 138) in the context of the Great War and the 1918 influenza epidemic.
