The library has a circulating collection of over 116,000 books, audiobooks, and DVDs. The library takes its name from a vanquished Pequot group of 80 to 100 who had earlier fled their home territory in the Mystic area and taken refuge with approximately 200 Sasqua people who inhabited the area that is now Fairfield.
