National Postal Museum Library

The National Postal Museum Library is one of twenty specialized libraries in the Smithsonian Institution Libraries system. The National Philatelic Collection was the basis of the Library when it was established in 1993.

With more than 40,000 books, journals, catalogues and archival documents, the National Postal Museum Library is among the world's largest postal history and philatelic research facilities.

Although the National Postal Museum Library focuses mainly on philately and postal service in the United States, the collections are international in scope. In particular, Canada, Great Britain, Germany and France are well represented. With more than 5,000 books, 6,000 serial titles, manuscript files, photographs and many auction and priced catalogues, the collection also includes major archival holdings, including files from the United States Post Office, the Highway Post Office, the Aerial Mail Service, the Railway Mail Service, and the Panama Canal Zone Post Office.
