Project Briefing: A Resource Discovery Service for the Library of Texas: Requirements, Architecture, and Interoperability Testing William E. Moen Texas Center for Digital Knowledge University of North Texas Kathleen R. Murray Texas Center for Digital Knowledge University of North Texas In the past several years, a number of states have initiated virtual library projects to enhance access to resources available through libraries and other information resource providers. Typically the resulting virtual library is deployed as a Web-based portal through which users may identify and access selected resources. Recent work at the Texas Center for Digital Knowledge (TxCDK) at the University of North Texas is demonstrating how attention to requirements, standards, architecture, and interoperability testing can provide the foundation for an extensible, services-oriented virtual library.
