Community Borrowers
Everyone in the community is welcome to consult the material in the Library. Those wishing to borrow Library materials may apply for a Library Card. Community borrower fees are $25/4-month period or $75/yr for the general adult public with appropriate ID. Community borrowers may borrow up to 10 books at any one time for a period of two weeks with up to 3 self-renewals permitted. The cards do not allow access to the Course Reserve Collection or interlibrary loan services. Access to the Library’s Web databases is also restricted to Carleton University students, faculty and staff through the Library’s site licensing agreements with service providers.
