Westwood’s main public library closes on Thursday after a 43-year run of service to the community, to be replaced in January when a better, bigger building opens next door.

Until then, residents can use a branch library in Islington, said library director Tom Viti. Although he’s not sad to see the cramped old building go, Viti said, he is grateful for what it has meant to generations of Westwood families and others who used it.
