What may be borrowed
It is recognized that interlibrary borrowing does not relieve any library of the responsibility for developing its own collection. Each library should provide the bulk of materials needed by its users for purposes of study, instruction, information and research.
The borrowing library should make every effort to exhaust its own resources before turning to interlibrary loan. It should also screen requests carefully before transmitting them to the Council, eliminating those which common sense indicates would not be supplied.
The borrowing library is responsible for returning loans promptly and in good condition. The borrowing library should respond quickly to overdue notices and is responsible for paying fees for lost books as levied by the lending library. The library should refuse to request books on interlibrary loan on behalf of borrowers who abuse the privilege.
