Together, the libraries of the schools of the Boston Theological Institute own over 4 million volumes in theology and related disciplines. You can browse highlights from our member library collections here. The collections are accessible to all BTI students and faculty. A new system for borrowing, replacing the BTI library card, was implemented on August 1, 2018. To gain access to BTI lending, you must opt-in for your information to be shared with each library. This will allow BTI libraries to verify that you attend a member school. View the full instructions for opting in for all students. 

Students who have a BTI Portal Account simply need to opt-in via the BTI Portal.

Students without a BTI Portal Account need to fill out the New Student Registration Form to opt-in. You will see this option at the bottom of the form. 

Faculty and Staff members need only present their current school ID when borrowing from another BTI library.

Borrowing Privileges and Procedures

BTI students and faculty may borrow books from any other BTI school library opon proof of school affiliation and completion of any registration required by the lending library. Books may be checked out in person or requested through inter-library loan (ILL). BTI alumni do not have borrowing privileges at BTI libraries but may be able to request a book through the school they attended. 


Unless requested by another bororwer, books may be renewed at the circulation desk of the lending library. Specific library renewal policies may differ. 


Books borrowed from other BTI libraries may be returned through the MLS (Massachusetts Library System) by leaving them at any BTI library circulation desk. 


Fines for overdue materials and replacement costs for lost materials are charged according to the policy of the lending library. Failure to pay fines or return recalled material can result in the loss of borrowing privileges at all BTI libraries.
