Post Instruction Manual for Versalog Slide Rule

Post Instruction Manual for Versalog Slide Rule

Usage conditions apply
This is a later printing of 1978.0800.02. Its citation information is: E. I. Fiesenheiser, Versalog Slide Rule Instruction Manual, with R. A. Budenholzer and B. A. Fisher (Chicago: Frederick Post Company, 1963). The text appears not to have been revised since these three Illinois Institute of Technology engineering professors helped invent the Versalog slide rule and wrote instructions for using it in 1951. Marks inside the front cover indicate this copy was offered for sale in January 1969 for $1.00.
