Bournemouth, Christchurch and Poole Council says contractors have begun work to remove reinforced autoclaved aerated concrete, known as RAAC, from the roof space above Poole Central Library.
The library, based in the Dolphin Centre, remains open and all services are continuing as normal.
The council says there is no immediate risk to visitors or staff, but customers should expect some noise and disruption while preparations and works take place.
RAAC was previously identified in the roof of The Hub at the Dolphin Centre in February 2025.
Councillor Andy Martin said the council will continue to monitor the library environment and keep residents updated if opening hours or services change.
The removal works are expected to take around one year.
