New users

ILLiad requires a WorldShare Interlibrary Loan subscription as it calls on the underlying WorldShare architecture for its communication with the OCLC ILL network, using WorldShare ILL web services to download and update both borrowing and lending requests.

To order ILLiad, please complete the ILLiad contract order form.

You may also request a demonstration, request a quote or contact an OCLC Library Services Consultant to discuss how ILLiad can help interlibrary loan at your library.
