KSK has a Section of Cheese Labels which publishes ranking lists of collections of cheese labels every 3rd year. Till 1975 only collectors from the former Czechoslovakia participated. Although in each of 15 international editions there were more Czechs than collectors from all other countries together, the project is really international, and collectors from France, Netherlands, Switzerland, and Czech Republic have been on the top of the list. The other participants were from Australia, Germany, Great Britain, Poland, Romania, Slovak Republic, former Soviet Union, Spain, and United States. In 1997 the ranking was published on the web (my web page) for the first time. Since 2000 it is published on web by KSK. A recent ranking (2024) can be found here . The following table reports the essential data from the previous ranking lists and my rank (I have not participated in 1974).
