What is an interlibrary loan?

An interlibrary loan (ILL) is a library service whereby cardholders may request to borrow materials from another library if the item is not owned by Grand County Library District or the Marmot Libraries. Generally, GCLD will utilize the system called SWIFT (mostly academic and public libraries participating from the Front Range area) to borrow an item not found within the GCLD or Marmot Library catalog. We ask that a local search be done in Marmot first, then an ILL form may be submitted.

An ILL should not be confused with a regular material request or an item hold which is a service of GCLD by which a user may request to be notified as soon as a book that has been checked out becomes available. The material is kept on the reserve shelf for a limited period of time (currently, GCLD holds items for 6 days and then returns the item to the shelf or to the lending library).
