Abstract
Popular for their ability to provide full-text linking, OpenURL link servers, such as SFX, can also interface with online catalogs and interlibrary loan modules, giving library users the ability to locate articles in print or request items not owned by their local institution. This article examines four different approaches to integrating print holding information into SFX, detailing the advantages and drawbacks of each approach. The ultimate goal is to provide end-users with comprehensive, dynamic access to the full range of core library services, including online full-text, print materials, and interlibrary loan.
