ISASC publishes a regular journal (Equilibrium, or EQM), which is a mine of information about scales and weights, with some related topics as well. Equilibrium is produced to a high standard, with many excellent photographs and illustrations. Copies of EQMs from 1979 onwards are occasionally available through Internet sources.
Articles, which are often contributions of original research of a learned nature (but are not peer-reviewed in advance of publication) are always welcomed by the Editor, whose details appear in the magazine. Joining the US organisation online is recommended.
