As the largest Mormon primary source from 1849 to 1851, the Frontier Guardian is crucial to understanding the Latter-day Saint experience at the Missouri River. Until now, historians have extracted only small sections of the paper, such as marriage announcements, obituaries, and advertisements, because of the Guardian‘s size. Although it is only four volumes, the newspaper contains eighty-one issues, each spanning four pages in length and divided into six columns. This translates into roughly four thousand single-spaced pages on 8.5″ x 11″ paper. Fortunately, the recent publication The Best of the Frontier Guardian along with its searchable dvd-rom of all eighty-one issues will help researchers explore the Mormon experience in Pottawattamie County, Iowa.
