After a series of problems with falling ceiling tiles at the new Westwood Public Library, town officials have again closed the High Street facility until the matter can be resolved. A notice on the town’s website apologized for the inconvenience. “Past fixes for the second floor ceiling have unfortunately not resolved the problem,’’ the notice said. “The Permanent Building Committee is putting together a team to address the issues and has authorized the closing until all safety concerns have been resolved.” Officials said the schedule of the Islington branch would be revised to coordinate the pick-up of reserved materials. The $13.9 million Westwood Public Library opened in July and has been closed several times in the last few months because of the tile problems. More information is available at westwoodlibrary.org.
