The Chelmsford Public Library consists of the Main library in Chelmsford Center and the Anna C. MacKay Branch Library in North Chelmsford. The Main Library opened a new 25,000 square foot addition on February 29th, 2000. The addition provided for handicapped accessibility, a large meeting room, a vibrant children's room, a teen area, and an improved reference and non-fiction area that houses over 40 computers with catalog and public Internet access.

The library has a collection of more than 140,000 items and includes books, periodicals, audio books, CDs, DVDs, videos and newspapers. We also offer a wide range of library programs for all ages and interests from the more traditional services of story time, reading groups, and author visits to computer workshops, concerts, star-gazing parties, and poetry slams
