The Textbook Exchange Network is a 501(c)(3) nonprofit that was founded at Tufts University in 2017. The mission of the Textbook Exchange Network (TEN) is to increase access to affordable learning materials. To achieve this, TEN provides software to run student-to-student exchanges that facilitates the communication between buyers and sellers. This enables students to avoid bookstore and middleman markups. TEN now saves students across the United States $100,000+ annually.
