The early history contained in the Book of Mormon is obtained from three sets of plates: the brass plates of Laban, the small plates of Nephi, and the large plates of Nephi. However, when Limhi's people join with the people of King Mosiah in the land of Zarahemla they bring with them two additional sets of plates: (1) their own records, which are known as the record of Zeniff, and (2) the "records which had been found by the people of Limhi," which are later identified as the records of Ether. (See Ether 1:1-2.) When Alma and his people come into the land of Zarahemla, they also evidently bring their own records with them. (See Mosiah 25:6 and also the superscription before Alma, chapter 23.)
