Scott catalogue

Catalog of the world's postage stamps

The Scott catalogue of postage stamps, published by Scott Publishing Company, now a subsidiary of Amos Media, is updated annually and lists all the stamps of the world that its editors recognize as issued for postal purposes. It is published in fourteen large volumes that include twelve volumes containing all the countries of the world that have ever issued postage stamps, the United States Specialized Catalog, and the 1840–1940 Classic Specialized Catalogue. The numbering system used by Scott to identify stamps is dominant among stamp collectors in the United States, Canada and Mexico.
