Tullidge wrote his history after he had taken part in the "New Movement." In it he brought together a great deal of information, including the text of important papers, which is necessary to an understanding of the growth and struggles of the church. The work was censored by a committee appointed by the Mormon authorities.
Bishop Whitney's history presents the pro-Mormon view of the church throughout. It is therefore wholly untrustworthy as a guide to opinion on the subjects treated, but, like Tullidge's, it supplies a good deal of material which is useful to the student who is prepared to estimate its statements at their true value.
The acquisition by the New York Public Library of the Berrian collection of books, early newspapers, and pamphlets on Mormonism, with the additions constantly made to this collection, places within the reach of the student all the material that is necessary for the formation of the fairest judgment on the subject.
