The Stony Brook University libraries offer a wide range of services to assist you in your research and studies.

Reference services include walk-in assistance, as well as telephone, email, and chat lines.

The Interlibrary Loan (ILL) service will locate the material at another library and obtain it for you at no charge, if the library does not own what you need.

Main/ Southampton/ Manhattan Inter-Campus Delivery is a service for students, faculty and staff to request circulating items like books and DVDs from Southampton & main campus branches.

In addition to circulating material (and sending out overdue notices), the Circulation Department maintains the collection of reserve materials selected by faculty for their courses.
