“A Shorter but True Account Was Given by Nephi”

Joseph F. McConkie, Robert L. Millet
Reference here appears to be to Nephi, son of Nephi, son of Helaman, who continued the writing on the large plates. The record to which reference is made is one covering the twenty-five-year period since the sign was given announcing the birth of Christ.
