Trinity has a library of over 70,000 volumes, especially strong in biblical studies and Anglican theology. Two professional librarians help with research and reference questions. Personal computers with access to the Internet are available in private rooms for students' use. The library participates in a nationwide interlibrary loan system, enabling students to borrow books that are not in Trinity's collection. Students are also welcome to use the libraries of several universities and theological schools in the Pittsburgh area.
Trinity owns a few apartments and houses for student housing across the street from the seminary.
The Annex, about a block away, is rented to ministries such as the South American Missionary Society, and Rock the World Youth Mission Alliance. Setting Ambridge has rich ethnic and religious traditions, and a strong feeling for the importance of family and community. Most students buy or rent homes in Ambridge and have been made welcome. Several faculty and staff, including John Rodgers, Allen Ross, and Sam Wilson have also chosen to live in Ambridge. The area around Ambridge provides shops and services for different lifestyles and budgets.
