The National Library of Ireland (NLI) has a rich collection of heraldic manuscripts and material, primarily dating from the early modern and modern periods.

This is of little surprise as the NLI is the home of the Office of the Chief Herald of Ireland which inherited the records of its institutional predecessor: the Office of the Ulster King of Arms which was established in 1552. The Library continues to add to this collection and in 2022 acquired a grant of arms issued in 1554 by the then Ulster King of Arms, Bartholomew Butler, which contains a superb illustration of Butler himself (MS L 559).
