MICHEL Catalogue

MICHEL-Briefmarken-Katalog  (Michel Catalog) is the largest and best-known stamp catalog in the German-speaking world. First published in 1910, it is considered one of the most important reference work in philately.
It was first issued as a price list specially made for the dealer Hugo Michel of Apolda. By 1920 it was split into two volumes - "Europe" and "Overseas", subsequently growing to the present-day size of about a dozen volumes covering the entire world, with additional specialized volumes bringing the total to some forty catalogs.
