The seminary library's primary mission is to participate in the theological and pastoral training of future priests, deacons, religious, and lay men and women, but it also serves the wider Church and general public as well. The library's primary users are the administration, faculty and currently-enrolled students of seminary programs, but we welcome visitors, local scholars, retreatants, and parish ministers, etc. The library and its staff consciously strive to cultivate core values such as respect, hospitality, diversity, collaboration, and excellence. Our goals and objectives are based on the belief that we are helping our users become lifelong learners who are at once well-rooted in the history and the patrimony of the Church, and ready to go forth and evangelize in the third millennium.

Holdings include: over 50,000 monographs and bound periodicals, several online databases, over 200 journal subscriptions, and over 600 audiovisual items. Our special collection of approximately 4,000 old and rare books is housed in the Bonaventure Room.

We welcome visitors and inquiries from the wider community. For more information on visiting, email us at: This email address is being protected from spambots. You need JavaScript enabled to view it.

The original library was based on a collection of books donated by generous clergy and other Long Islanders when the seminary opened in 1930. For many years, the library was on the second floor of the seminary, and access to the collection was limited. In the 1970s, as the seminary prepared for accreditation from Middle States and the Association of Theological Schools, the teaching collection was re-classified and moved to its current home on the fourth floor of the building. Since then, the collection has grown in depth and variety. The library automated in 2005, and the staff continues to utilize new technologies as it serves the Church on Long Island.
