550 pages of Instructions from models of K&E slide rules that are no longer produced. This is a reference work to preserve slide rules manuals. Many companies, such as Keuffel & Esser, are no longer in business after the 1970's. The instruction manuals were rarely ever sold separately from the slide rules and many were lost over time. This preservation project is to provide a composite hard copy book and quality digital reprints of restored instructions from the most popular manufacturer's slide rule models. K&E II Volume 32 is a continuation of K&E Volume 2 that was previously published. There were a numerous model numbers and associated manuals from K&E, so more more Volumes are required to complete the preservation project.
