Available Services


OCLC® Interlibrary Loan Service
Includes information on ILL Transfer, ILL Fee Management (IFM) the Name-Address Directory, Custom Holdings, Usage Reports, and ILL Document Suppliers Program.

OCLC ILL Fee Management Service
The OCLC ILL Fee Management service (IFM) helps libraries significantly reduce administrative costs by allowing users to pay—and be paid for—ILL lending charges through their OCLC invoices.

OCLC ILLiad®
OCLC ILLiad software is a comprehensive interlibrary loan management system that automates routine borrowing and lending functions within a library's interlibrary loan department. OCLC ILLiad also provides a web interface that empowers library end users to submit ILL requests and allows them to track the status of their requests 24 hours a day, 7 days a week, without library staff intervention. OCLC ILLiad software includes interfaces to the OCLC ILL service, the National Library of Medicine's DOCLINE service, and RLG's RLIN ILL service.

OCLC Local Holdings Maintenance
OCLC Local Holdings helps you maintain accurate, current holdings information. This information supports interlibrary loan by providing your library's holdings for materials in any format, including serials. By making all aspects of the collection known, it also supports collection development. It provides finding tools for local users and staff and assists remote users in deciding whether to travel to the library to use the collection. Finally, it supports consortial sharing, cooperative collection development, and acquisition.

OCLC ILL Direct Request
Direct Request lets a user place a request right from an online citation. That request can then bypass staff review and directly enter the WorldCat Resource Sharing system. Your Direct Request profile sets the criteria that determine if requests are manually processed or automatically sent to an eligible lender, and whether sharing is available for items you already own. Turnaround time decreases, backlogs shrink, and your staff can focus on other priorities.
