Want to dig a lot deeper about a slide rule?

In these company archives, you can find very detailed info about the rules and models they made, the company and its history. Some rule makers were in business almost 100 years, and their histories and products are fascinating. Some major makers still survive today, but without any help from slide rules, as their businesses are now quite different. In the 1960's, the industry was at its most sophisticated, and there were large slide rule manufacturers all over the world, each with their unique styles and features. This industry and technology survives today mainly in the form of slide charts, and the hearts of collectors.

We also have archives organized by function, like circular rules, exotic and unusual rules, perrygrafs and slide charts, giant rules and (yes) slide rules you WEAR.

There are some interesting surprises hiding in the archives, and all of them are worth a quick visit. You will discover in your tour that you can still have custom slide rules (well, slide charts) made for you today for a surprisingly low price. You will also discover that you could actually have gotten a Zippo lighter with a slide rule built in at one time, and that you can now get software to emulate a slide rule on your PC.
