"By preserving, expanding, and providing enhanced access to its world-renowned collection, the John Carter Brown Library inspires scholarship, stimulates innovative and creative engagement with its materials, and connects communities around the world to the history and culture of the early Americas."

In 2015, the Board of Governors of the JCB agreed to a new mission statement that emphasized the Library's collection at the heart of the institution, but also paid close attention to its role in connecting communities to the history and culture of the Americas. The JCB's informal tagline – Collecting and Connecting the Americas – derives from this mission statement and highlights the aspiration to connect communities through the Library's unique collection.
