|Hardiman's History of Galway|
James Hardiman (1782–1855), also known as Séamus Ó hArgadáin, was a librarian at Queen's College, Galway.
The university library now bears his name.
Hardiman was born in Westport, County Mayo, in the west of Ireland around 1782. His father owned a small estate in County Mayo. He was trained as a lawyer and became sub-commissioner of public records in Dublin Castle. He was an active member of the Royal Irish Academy, and collected and rescued many examples of Irish traditional music.
In 1855, shortly after its foundation, Hardiman became librarian of Queen's College, Galway.
The university library was later named in his honour.
Hardiman Road in Drumcondra, Dublin is named after him.
