Scope and arrangement
The collection is divided into six parts; Mormon material, writings, correspondence, unsorted papers, photographs, and printed ephemera. The Mormon documents include correspondence, 1846-1931, with letters 1846 - 1852 to Brigham Young possibly all from his wives, and letters 1878-1882 to and from James Cobb concerning the origin of the Book of Mormon. In addition, there is correspondence of Schroeder which is concerned with Mormonism. Articles such as "Mormonism and Prostitution", "incest Taught and Practiced", and "Mormonism and the Erotogenesis of Religion" are among the writings in this category. Unsorted documents are clippings, notes and printed matter.
Schroeder's writings include printed copies and a few typescripts; there is one notebook of "Thumbnail Essays". These writings represent only a fragment of Schroeder's total output. The correspondence includes several verse letters from Paul Mnason an eccentric friend, and that between Schroeder and Guy Aldred, Susan Earl, and W. J. Cushing, along with an open letter with Rawlins and Henderson concerning political matters. In addition there is business correspondence and letters with publishers, in particular Vladimir Blad. Unsorted material incorporates clippings, printed matter, index cards which catalogue book reviews and periodicals, and three law books, one of which records the Brigham Roberts case. Photographs include glass negatives, along with photographs, possibly of Schroeder's parents.
Printed esoterica collected by Schroeder is concerned with religious, legal, political, medical and other topics.
