Many notebooks in the collection sustained water damage and mold infestation. When notebook materials are in a letter-size manuscript box, it indicats the original notebook was badly damaged and discarded. The photograph pages within each notebook were cleaned of mold and housed in polyester L-sleeves. Although safe for general use, those with severe allergies or respiratory diseases should handle with caution.
