Attention Medford seniors: Have you visited the new Charlotte & William Bloomberg Medford Public Library building, which opened in January? If not, sign up for the Medford Council on Aging’s free van transportation to take you over. The van will leave the Medford Senior Center at 10:30 a.m. and return 1 p.m., allowing plenty of time to wander the new library with its vast amount of books, resources, and more. Limited to 14 passengers. Sign up at the Senior Center or call 781-396-6010.
