Slide Rules -- Manuals & Documentation

Manuals & Documentation

Keuffel & Esser, Pickett, Dietzgen, and other major slide rule companies often included an instruction manual in the purchase of the instrument. Some donors have provided these booklets and other paper items, such as advertising flyers, directions for cleaning slide rules, warranty certificates, and even cash register receipts. The Museum of Science & Industry in Chicago previously owned and displayed one of the Thacher cylindrical slide rules, and it arrived with its exhibit label. To see the instruction manuals alongside the objects they explained, please see the index by makers & retailers page.
