Purpose of the Policy

To satisfy the disparate needs and interests of patrons using the MOBIUS library catalogs, multiple points of retrieval must be made available in catalog records. Whether shared materials are requested by means of traditional interlibrary loan, direct patron borrowing through the MOBIUS union catalog, or via electronic databases, MOBIUS catalog records must be indexed to promote acquisition of needed information and to provide full access options.
