The 2013 edition of the Book of Mormon, Doctrine and Covenants, and Pearl of Great Price contains all of the study aids contained in the 1981 edition and includes revisions to the study aids, several new photos, updated maps, and adjustments to section and chapter headings. The style and format of titles, tables of contents, abbreviations pages, and other study aids have been standardized to improve the reader’s experience; however, the adjustments have not been so extensive as to require members to purchase the new edition to stay current with either the Church curriculum or personal study.
