In their gratitude for a modern prophet, Latter-day Saints must face the possibility that they might know him rather superficially. Available books collecting key quotations from Joseph Smith are no guarantee that readers are really exposed to the range and depth of principles that he proclaimed and died for. Since Mormon literature is notorious for inadequate indexing, one result could be recurrent discussion of issues that does not utilize available doctrinal resources. Matthews' work is a major step toward correcting such a defect in the use of the Prophet's statements, and no informed Latter-day Saint can afford to be without a simple reference tool of this importance. Matthews deserves more than mere credit for producing it; it should be included in future printings of the Teachings of the Prophet Joseph Smith.
