All high-resolution scans have been reduced to 75 dpi, so what you see on the screen should be roughly the actual size of the ruler. Please do not use them anywhere else without letting me know in advance – thanks! Slide rule style calculators are standard reference tools for many industries. They are easier to use than traditional slide rules, more convenient than electronic calculators, and cheaper than computers and smartphones. You can afford to put one in the hands of anyone who buys what you sell. A brief review of sliderule.ca was reported in the online edition of the technology business magazine Business 2.0 entitled “When Slide Rules Ruled” (July 18, 2001). If you want to learn more about collecting slide rules, visit The Oughtred Society. It is an international organization dedicated to the history and collection of slide rules and related computing devices. For me, slide rules probably carry a sense of nostalgia for past scientific times. Using one will give you a much better idea of what numbers really mean than using a calculator or computer. They are remarkable technological instruments, built with precision and reliability, and are as useful today as they were on the day they were first manufactured. Many are also inherently beautiful, with their celluloid-covered wood, metal-framed glass sliders, and colorful leather bags. I do not intend to collect slide rules. But I find their incredible variety and functionality amazing and fascinating.
If you read these pages, then you can do it too, and therefore no further explanation is necessary. In any case, I hope you like the site! A link to sliderule.ca (January 19, 2002) that generated a lot of traffic came from the online collection of unusual websites known as Memepool. I think slide rules hit a common meme among people (I apologize to Richard Dawkins for the pun). I guess we need to make a few comments. Probably no other technological tool in the history of the modern world has been used so widely for so long, only to disappear virtually overnight. The form and characteristics of the slide rule have been revised for centuries, and there are probably few people over the age of 50 today who have not used it regularly at school or work at some point in their lives. But with the advent of inexpensive calculators in the early 1970s, slide rules quickly followed the path of sleeping. What`s even more remarkable is that today it`s possible to get 140+ functional science calculators for just $5! Polite greetings! This page contains scans and descriptions of my collection of slide rules, as well as several pages of (hopefully) useful general information. I haven`t actively collected new rules in several years, but I`ve maintained the site as a resource for others.
