Improvements to Malton library as part of carbon-cutting measures at numerous County Council buildings, including schools and care homes, will now take place in October rather than this month.
The work, which involves the replacement of windows, will be paid for from Government public sector decarbonisation funding.
The library was due to close for the work from September 6 until September 25.
However, a delay in the supply of materials for the windows means the work has been postponed. Instead, the library will close for the work from 18 October, reopening on 8 November.
Loan periods will be adjusted so that no borrowed items will be due for return during the closure, and home library service deliveries will be covered.
County Councillor Greg White, Executive Member for Libraries, said: “Given this short delay, we wanted to inform our customers that the library will now be open as usual during September. The work to be done in October will not only enhance the library, but is part of a wider programme bringing benefits across the county.
“While the library is closed, we hope regular users can visit other libraries or take advantage of our fantastic online resources.”
