29 May: Bank holiday in Northern Ireland
There's a public holiday in Northern Ireland on Monday, 29 May, so all repositories, archives and libraries will be closed.
The Linen Hall Library in Belfast will be open on Saturday, but not Monday.
While Northern Ireland takes the day off, it's a normal working day in the Republic of Ireland, where the next bank holiday is a week later (5 June).
