All of the following are bibliographic utilities involved in resource sharing except

• A. OCLC
• B. DYNIX
• C. RLIN
• D. UTLAS

Answer: (B)

Resource sharing relies on bibliographic utilities that maintain centralized catalogs and holdings so libraries can locate and borrow items for patrons. OCLC is a well-known cooperative cataloging and interlibrary loan network, central to sharing records and requests. RLIN served as another bibliographic utility for cataloging and distributing records among member libraries. UTLAS operated as a regional system that supported shared cataloging data and interlibrary loan activities. DYNIX, on the other hand, is a library automation system used to manage local library functions like acquisitions, cataloging, and circulation. It serves individual libraries rather than acting as a cooperative bibliographic network, so it isn’t a bibliographic utility involved in resource sharing.
