3.10 More Information
Slide Rule manufacturers of the 20th century usually provided instruction booklets/leaflets for the use of their slide rules, many of which are hard to come by 100 years later. Often times expanded texts – in either hard-bound or soft-bound varieties – were written and sold by the manufacturers as well, and often can be found for sale in used book stores. And of course there were several authors who wrote books on the subject without the bias of a single manufacturer. The Chapter Books, Manuals, and Sheets contains a few books which I have stumbled upon over the past few years and have added to the collection.
