Thanks to the generous donation of Hubbard Hall, four passes are available to library patrons for every Theatre and Music performance of the Hubbard Hall 2016-2017 season for FREE, including this weekend’s performance of John Sheldon’s My Journey to the Center of the Earth. Patrons just have to stop by the front desk at the library to request tickets for a specific performance. If you have not had the chance to see a production at Hubbard Hall, here is your chance! Passes are available on a first come, first served basis. For more information about passes, please call the Cambridge Public at 677-2443 or stop by during library hours.
