Who and Where

More than 1000 slide rule collectors are known world-wide. Looking at the number of buyers on internet (at eBay and dealers), there must be many thousands of other interested people. Some of them are organised in country- or language-focused groups, but others are more "lone hunters".At the moment, 5 groups of slide rule collectors are known, with the observation that some individuals belong to more than one group .

OS Logo small.jpg (37288 bytes)The Oughtred Society (OS), a formal "non-profit public benefit" organisation in the USA, is since 1991 the largest group of slide rule collectors. More than 400 OS-members exist world-wide, of which about 100 in Europe. Since 2003 the Oughtred Society has extended its interest to "Historic Calculating Tools".

International Meetings

Since 1995, an "International Meeting for Slide Rule Collectors" (IM) has been organised every year in Europe.
Each IM is organised by collectors from one country. The programme consists as a rule of a swap fair, presentations by and to collectors, and ample opportunity for social events and talking with old and new collector friends.
Proceedings have been published during each IM, documenting all presentations given.

For most IM Proceedings, it is possible to order back-copies, for  prices around 20 EURO, excluding shipping costs.  ask for more information.
