The Global Philatelic Library is an initiative to provide a consolidated listing of philatelic publications, archives, museum items etc. held by libraries.
So far 27 libraries have contributed their listings.
By clicking on the APRL or RPSL library logos to the left you will be redirected to the ‘union catalogues’ developed by those organisations to hold copies of holdings for several libraries. Eventually, a free-standing search function / database will be provided.
