Interested in Slide Rules
and other Calculating Devices?

Join the Oughtred Society!
We invite all to join us
in this fascinating pursuit.

As a member of The Oughtred Society, you will enjoy the following benefits:

  1. You will become part of an enthusiastic group of collectors from around the world and annually receive two editions of The Journal of the Oughtred Society (JOS). This internationally acclaimed journal is considered the most authoritative source on slide rules and mechanical calculators. Each issue contains a wealth of information about makes and makers, models, uses, history and much more. Members are encouraged to submit articles.

  2. Members (and non-members) may buy back issues of the JOS , from 1991 to present.

  3. You will regularly receive an updated Members Directory, a great resource for finding and communicating with other like-minded collectors, dealers and aficionados.

  4. From time to time domestic face-to-face or online ZOOM-style meetings will be held where members and non-members can exchange information, display items from their collections and meet with fellow collectors. At such meetings but only for members, there is opportunity to take part in an auction. Many kinds of slide rules and calculators are auctioned off, from the everyday to the rare.

Memberships are for a calendar year and run from January 1 through to December 31. Membership dues are payable on January 1. This applies both to new memberships and renewals. The two types of membership reflect the geographic makeup of the membership and associated postal charges:

From 2024, in response to member feedback, the society offers two options for each type of membership. Members can opt to receive printed hard-copy versions of the JOS or digital PDF- only versions of the JOS. Members opting for a hard-copy of the JOS will also get the digital PDF version.

You can use your credit card or debit card if you pay via PayPal. Alternatively you can pay directly by a cheque in US dollars but because of overseas bank clearing charges, this is usually only of interest to Domestic members. When we receive your payment you will be sent any materials already published in the current calendar year.

1. New and Renewing Members.
