The Linen Hall Library in Belfast has undergone a deep clean in preparation for the easing of coronavirus restrictions.
Library staff posted a video today showing a cleaner spraying disinfectant on some of the library's desks.
Some libraries are due to reopen, with expected limits on the number of people allowed into a building, as part of the second stage of the assembly's plans to ease lockdown.

The library is the oldest in Belfast and the last subscribing library in Ireland.
Founded in 1788, it celebrated its 232nd birthday earlier this month.
The library holds treasures including the earliest printed edition of the Declaration of Independence outside of the United States and a first edition of James Joyce's Ulysses.
