As the author Osborne Widtsoe (Elder John A. Widtsoe’s brother) wrote, “The following chapters on the subject of the Restoration are the outcome of an invitation to write, during the winter of 1910-11, a series of lessons for the Young Ladies’ Mutual Improvement Association.” The result, now available as a free e-book on Project Gutenberg, was originally published with a preface by then-Apostle Joseph Fielding Smith, where he stated:
This book, prepared by Elder Osborne J. P. Widtsoe, dealing with the important subject of the restoration of the everlasting Gospel, should be read and its contents carefully considered by those who are seeking after truth. It treats the restoration clearly, and places before the people many things that have not been generally considered heretofore. It will be a means of strengthening the faith of the youth of Israel and will impart information that is invaluable. May the spirit of truth accompany the work and rest upon all those who diligently read it with a desire to learn of and profit by the restoration of the Gospel!
