Four years ago, I brought up resources to assist in study of the Doctrine and Covenants. There were some significant books that were mentioned, but not as many as I had assumed there would be. That launched me on a path that has led to my book, Fragments of Revelation: Exploring the Book of Doctrine and Covenants. In addition, I have continued to search out relevant books and other literature about the Doctrine and Covenants. That work of seeking out resources, combined with the extensive interviewing work of the Latter-day Saint history blog From the Desk, is brought together in a new Come Follow Me 2025: Doctrine and Covenants Resources page.
This 2025 Come, Follow Me page contains several elements, including key insights from interviews that draw on the expertise of dozens of the top scholars in Mormon Studies in recent years; quotes about the Doctrine and Covenants from notable leaders of the Church; the schedule for Come, Follow Me in 2025 with links to each week’s materials; and a collection of “further reading” that links out to a large number of books, articles, and other literature that relate closely to the Doctrine and Covenants. The hope is that this will be a useful and fruitful resource for studying the Doctrine and Covenants for years to come. (As a side note, I recognize that I likely have overlooked some resources in my work in compiling, thus I welcome comments about resources that can and should be added or other suggestions for improvement.)
How about the four volume set of A Commentary On the Doctrine and Covenants by Stephen Robinson and Dean Garrett? I have found this very helpful.
