The Edward Worth Library, is named after its collector, the early eighteenth-century Dublin physician, Dr Edward Worth (1676–1733), who bequeathed his library of c. 4,300 volumes to Dr Steevens’ Hospital, Dublin, an institution of which he was a Trustee.
Today, it is regarded as the most important medical collection of early modern Ireland. Its extensive medical holdings reflect Worth’s interest in all areas of medical practice, while the rest of his library points to his abiding interest in the history of science and the history of the book as material object.
