Slide RulesManuals & 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.

- These three photographs relate to the hydraulic slide rule developed for calculations relating to pumps and pipelines at the Georgia Iron Works (2009.0100.01). A snapshot from 1961 shows the slide rule as it was first designed. A second image shows the designer, Danforth W. Hagler, in an office in the 1960s. The third, which is somewhat later, shows Hagler at the console of an IBM 1130 computer. In that photograph, an oversized version of the slide rule he invented is mounted on the wall.
