Stamp catalogue

A stamp catalog (or stamp catalogue) is a catalog of postage stamp types with descriptions and prices.

The stamp catalog is an essential tool of philately and stamp collecting. Stamp catalogs are part of philatelic literature.

The first stamp catalog was published in France by Oscar Berger-Levrault on 17 September 1861 and the first illustrated catalog by Alfred Potiquet in December 1861 (based on the earlier work).

The first catalogs in Great Britain were published in 1862 by Frederick Booty,Mount Brown, and Dr. John Edward Gray. The first in the United States was The Stamp Collector's Manual by A.C. Kline (a pseudonym for John William Kline), also 1862.

Older catalogs are still widely used by collectors as they may contain information not found in current catalogs and not all collectors are concerned about prices.

Originally catalogs were just dealers' price lists, though today that is rarely the case. Over time, as philately developed, catalogs tended to accumulate additional supporting details about the stamps, such as dates of issue, color variations, and so forth. As their use by collectors became widespread, the catalogs came to define what was and was not a legitimate stamp, since many collectors would avoid stamps not described in the catalog. In recent years, the Internet has become a common resource for information about stamps. Some catalogs have an on-line version while others are available only on-line.

The following catalogs have a worldwide coverage:

These are large undertakings, since there are thousands of new stamps to describe each year, and the prices of all stamps may go up or down. For publishers that are not dealers, the prices are estimated by data from dealers and auctions.

In addition, the catalog publishers usually put out specialized volumes with additional details, generally by nationality: Michel has a specialized German catalog, Scott a specialized US catalog, and so forth.

Many countries have their own "national catalogs", typically put out by a leading publisher or dealer in that country. Postal administrations may themselves put out catalogs, although they tend to be aimed at less-experienced collectors, and rarely provide fully detailed stamp data. Some notable country catalogs include:
