The Maryland Historical Society’s H. Furlong Baldwin Library enables researchers, students, teachers, and others to have access to the records of Maryland’s past while preserving irreplaceable historical materials for future generations.
The sizeable collection of books, journals, manuscripts, newspapers, maps, prints, obsolete currency, oral histories, ephemera, and microfilm which the library makes available to the public via the Reference Department and Special Collections is one of the nation’s most extensive and important historical resources.
Among the more than 7 million items at the H. Furlong Baldwin Library are Francis Scott Key’s original manuscript of "The Star-Spangled Banner," papers of Maryland’s colonial governors and signers of the Declaration of Independence, including the Carroll Papers, the Lloyd Papers, Tilghman Family Papers, over 900,000 photographs, and considerable genealogical resources.
MdHS strives to make its collections even more accessible through the Collections Online database.
