International Groups and Activities

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, 6 groups of slide rule collectors are known, with the observation that some individuals belong to more than one group.

International Meetings

The organisers of an IM pass the “IM Challenge drum

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.
Old Proceedings can be accessed via Rod Lovett's Literature Search.

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