Resources

Other adding machines are found scattered in the NMAH collections. The mathematics collection also has collections of adders, bookkeeping machines, and calculating machines, which are described separately. Notable collections of adding machines include those of the CNAM in Paris, the Science Museum in London, and the Arithmeum in Bonn. Numerous other repositories, as well as individuals, have one or more important machines.

Useful sources for the study of adding machines include trade literature produced by manufacturers and trade journals such as Typewriter Topics and Office Equipment Topics (later Business Equipment Topics). Several volumes produced for office machine dealers are also of help. Museum catalogs, scattered articles, and a few books offer useful perspectives. This list is limited to publications discussing products of several companies. Specific references are also given in discussions of individual machines.
