This page collects only issues released during the year 2001 (period between September and October).  For issues to come (announced) see the latest information.

As it is not such obvious as it looks to find this information, this list is probably not yet complete. In certain countries, joint issues are often announced on the day of the issue and sometimes it takes months before this information and the corresponding stamps reach us. Data on missing issues or supplementary information, particularly for countries, which are producing joint issues exceptionally, will be highly appreciated.
