Zumstein catalog

It has been issued regularly since 1909 and is considered to be an important reference work of Swiss philately.

The catalog is produced by the Swiss company Zumstein & Cie in Bern.

While their main product is a catalog for the stamps of Switzerland and neighboring country Liechtenstein, updated annually, they also publish catalogs for "Europa West" (Western Europe) and "Europa Ost" (Eastern Europe).

In addition, they produce a lengthier specialized catalog for Switzerland, as well as a number of monographs on topics in Swiss philately.
