This is a catalog of all the different types of postage meter stamps ever used to frank mail in the world. It organizes and categorizes the stamps by their appearance (design format) rather than the meter model that printed them. It is thus a STAMP catalog for use primarily by stamp collectors and is not a meter (machine) catalog. It is an expansion of The International Postage Meter Stamp Catalog, written and published by Joel Hawkins and Rick Stambaugh in 2005, and its 2008 Supplement.
International Stamp Meter Catalog
Postage meters first appeared experimentally at the end of the 19th century and came into general use worldwide starting in the 1920s. By the 1960s more mail was being franked by postage meter than with traditional adhesive stamps. The trend continues today as mechanical postage meters are displaced by newer and more versatile digital franking machines and systems.
