This collection is not noted on previous inventories. It appears that the monograph, the "History of Stanislaus County," was used as a journal or notebook for holding collected articles and handwritten notes. Articles are interspersed between the pages and appear to relate topically to the published content. Because of the name of "George Tinkham" on the collection box, it is inferred, though not confirmed, that the collection is comprised of notes and collected research in authoring the "History of Stanislaus County California : with biographical sketches of the leading men and women of the county who have been identified with its growth and development from the early days to the present."
