September 17th is considered the anniversary of the signing of the US Constitution, and, to commemorate, we are giving out pocket-sized Constitutions on Thursday, September 17, 2026, at the Information & Borrowing Desk and the Research Help Desk on Goldfarb Level 1. Quantities are limited, so get yours before they are gone!  

We'll also be holding a Voter Registration Celebration from noon-7pm. Register to vote in your home state or here in MA. Apply for a mail-in ballot if you need one. Or just swing by to say hi and grab some candy!

Also, in honor of Constitution Day, Louis Dembitz Brandeis’ copy of the United States Constitution Annotated is on display near the Registrar Office on Goldfarb Level 1. On Wednesday, September 17, the Elsie O. and Philip D. Sang Signers of the Constitution collection will be available for review for the public in the Archives Reading Room on Goldfarb Level 2, and facsimiles from the collection will be available on Goldfarb Level 1. Don't worry if you can't make it that day: this collection is always free and open to the public! This collection contains 50 original letters, documents, and portraits of the original signers of the U.S. Constitution, related material, and one oversize color portrait of Alexander Hamilton. The letters and documents range in date from 1759 to 1825.
