This volume, the 16th and last in the current series of reprints, is translated from the German original of 1925 and provides a very fine picture of the state of the mechanical calculator industry in 1925. After an introduction that describes the seven major types of machines that had been produced by 1925, Martin offers a list of specific makers, arranged by the date when they first patented or produced a calculating machine, and a quite detailed description of the devices themselves, many of which are illustrated.
