Town Meeting this week will decide whether to authorize selectmen to sell the former library building on the corner of Common Street and Lewis Avenue. A previous proposal to demolish the structure is off the table, according to Town Administrator Michael E. Boynton. He said businessman Albert Giandomenico has expressed interest in buying and renovating the old library. If Town Meeting approves the idea, the town would have to go through a formal bid process to sell the building, Boynton said. The new library opened this spring. Town Meeting starts Monday at 7:30 p.m. in Walpole High School.
