It seems to me that no slide rule site would be complete without a section discussing some of the available books on the subject. On this page, I have decided to list all the books currently in my collection, along with some editorial comments to hopefully help you separate the wheat from the chaff. I have divided this page into two main categories: modern books for collectors , and original slide rule instruction books . I generally haven't included rule-specific manuals on this page, as these are presented with the corresponding rule on my site when available. If nothing else, I hope you find the information here useful as a rough guide to the available slide rule literature.

The following books are written specifically for slide rule collectors, and are all currently in press. However, given their somewhat esoteric nature they can be hard to find, so you might want to order them directly from the publisher. Links are provided below, where available.

Originally published as several volumes in the 1920's, Cajori's classic has recently been reprinted and can still be ordered directly from the new publisher. This relatively short book is a heavily referenced and annotated history of the slide rule up to that time. The modern reprinting is an excellent resource for those more interested in the serious history of the slide rule as opposed to modern collecting.
