The Book of Omni is narrated as a combined composition by five different authors, each of which contribute a varying amount of content.
[2] The first author, Omni, fought in wars against the Lamanites, but calls himself a wicked man, stating that he hasn't followed God's commandments.
[10] According to Amaleki, because Mosiah was a seer, the Mulekites asked him to interpret a stone their people found that tells the story of a Jaredite named Coriantumr.
He states at the close of the book that, having no descendants to carry on the record-keeping, he will give the records to King Benjamin.
[15] According to authors Fatimah Salleh and Margaret Hemming, Omni wrote in order to maintain a record of the genealogical line.
[17] Additionally, Grant Hardy suggests that the contributors to the Book of Omni treated record-keeping as "a genealogical responsibility rather than an opportunity for preaching or testifying.
[19] Terryl Givens claims that Omni wrote in a manner that suggests he believed the Nephites would eventually die out.
[20] Adopting Robyn Warhol's term, professor of English at Vermont University Elizabeth Fenton calls the style of the Book of Omni "unnarration" due to a large lack of events while maintaining a "narrative voice.
