Oughtred SocietyThe Second Edition Oughtred Society Slide Rule Reference Manual

CLICK for a bigger PIC!!* Many people have asked for a comprehensive and well illustrated overview of slide rules that covers everything from operation and care to construction, as well as makers to materials. Something that would be useful and interesting to students, collectors, hobbyists, and teachers, without being too complex, pedantic or boring, as textbooks and manuals tend to be. This was an interesting task, and many people world-wide have worked very hard for almost a year to create something worthwhile to address this need. The first edition sold out a thousand copies quickly, and for almost a year afterwards, nothing further was available.
* This is the second edition of the Oughtred Society Slide Rule Reference Manual, compiled with help from collectors all over the world, and organized, written, photographed and designed by talented volunteers from the Oughtred Society. An incredibly rich visual publication, it has almost 100 color photos. The second edition has all corrections and additions included, and compressed spacing to reduce wasted white space, as noted on the OS web site. There is at least one color photo on almost every page of the book except the index and table of contents. Although the slide rule has a wonderful history stretching back for centuries, the latest digital technology and internet collaboration was used to create and print this work, and in fact, to allow you to read this information, which is no small irony. There are only 190 copies available in this second edition press run (400 total printed), so don't miss out on your chance to get this very useful reference. The second edition now has the title on the spine (THE orignal was blank), so it's easier to find on a shelf.
High Quality, Perfect Bound Color Cover & 97 Photographs 102 Pages 8.5" x 11" Letter Size Pages US$35 per Copy +shipping

How the Book is Organized:

Preface:
The Oughtred Society was founded in 1991 by a group of slide rule collectors and is dedicated to the preservation and history of slide rules and mechanical calculating devices. In the past 13 years, it has evolved to an international organization of some 400 members. It is noted for its highly acclaimed Journal of The Oughtred Society, published twice per year. The Society's activities are carried out by members who volunteer to do various jobs and projects. Membership is open to anyone. Additional information and a membership application are available in the brochure at the end of this manual.

This is the first new slide rule manual to be published in many years. It contains traditional instructions for use of the slide rule, highlighted by many color photos of slide rules and other items, plus much additional contemporary information, including chapters on such subjects as Slide Rules and the Internet; Major Companies and Some of Their Most Common Models (with color photos of all); Collecting Slide Rules; Cleaning and Caring for Your Slide Rule.

The information presented and the language used in this manual are intentionally as basic as possible. We hope you will find it to be easy to read as well as informative, and that the "how to" instructions and examples are easy to follow. For complex mathematics and concepts we refer you to the many existing manuals of the past.

With this new manual, The Oughtred Society wishes to introduce itself and to provide a service to the great numbers of slide rule aficionados, collectors and users with whom it currently is not acquainted. In doing this, the Society extends an invitation to all to join us in this fascinating pursuit.
