StampData is an experimental project to build an advanced stamp catalog and collection organizer.
StampData is different from other online catalogs in its deeper knowledge of philately. It automatically sorts stamps by date and face values, it has links from overprints to the types overprinted, and it has links from the stamps to the people and things they depict. It also links stamps to Wikipedia and other websites.
