Scope and Contents Boxes 41-47 contain Olpin's teaching materials that were originally in binders. The contents have been taken out of the binders and given a numbering system to distinguish them from each other. For example, box 41, folders 1-2, are from binder #1, as indicated on the folders. These materials may also include other schooling or miscellaneous papers but remain grouped with their respective binders to maintain original order.
