  2. Presentation Overview ZLOT Overview -- TLA Conference, April 2002

  3. The Library of Texas (LOT) • A statewide initiative building on • The evolving telecommunications infrastructure • Computing and networking technologies • The treasures and resources of Texas libraries • Overarching goal • Provide services and resources that extend the reach and range of Texans to information ZLOT Overview -- TLA Conference, April 2002

  4. Characterizing the LOT • A virtual library • An environment for provision of • Services • Resources • Not a digital library • Not all resources available are in digital/electronic form • An evolving product that responds to • Users’ needs • Available resources • Current and emerging technologies ZLOT Overview -- TLA Conference, April 2002

  5. Virtual library architecture defined by needs of Services UserGroups respond to needs of Services offer & use resources Resources Resources are collected, organized, managed using technology Technology ZLOT Overview -- TLA Conference, April 2002

  6. LOT Architecture • Services-based • Identifies components and their interaction in the support of virtual library services The ZLOT project is identifying some of the services and requirements ZLOT Overview -- TLA Conference, April 2002

  7. ZLOT project • Z Implementation Component of the Library of Texas • Developing a standards-based approach for the virtual library • Project Focus • Easing access to a range of library resources • Identifying requirements for resource discovery across library catalogs and online databases • Demonstrating feasibility and utility of resource discovery tools • ZLOT Project website: http://www.unt.edu/zlot ZLOT Overview -- TLA Conference, April 2002

  8. ZLOT methodology • Identify requirements • 4 focus groups (academic and public librarians) • Describe requirements for review • Build consensus on requirements through ZLOT advisory group • Describe existing technology landscape • Survey all public and academic libraries • Develop specifications for resource discovery tools • Searching across library online catalogs • Searching across online databases • Develop framework for document delivery • Building upon current resource sharing through ILL • Identifying supplemental approaches • Coordinate proof of concept implementations • Plan and conduct evaluation ZLOT Overview -- TLA Conference, April 2002

  9. Resource discovery services • Resource discovery services • Extends the reach and range of a user across • Organizational, collections, and format boundaries • A variety of tools and approaches for • Discovering the existence of appropriate resources • Identifying and selecting useful resources • Search and retrieval services are core • A common interface for • Searching one database at a time • Searching multiple but similar databases (e.g. library catalogs) • Searching multiple but diverse databases (e.g., TexShare databases) ZLOT Overview -- TLA Conference, April 2002

  11. Preliminary requirements: Resource Discovery • Diversity of libraries = diversity of requirements • Public and smaller academic libraries: • Importance of a common interface (simple and advanced) for searching across resources • Common LOT interface with customizable local library presence • Tools to help users select resources to search • Multilingual interfaces • Well-organized results (by topic, by type of resource) • Indications of availability and “how to get” ZLOT Overview -- TLA Conference, April 2002

  12. Technology inventory survey • Critical information needed to plan the evolution of ZLOT • Survey requests information on current technology in libraries • To be sent out within the next two weeks • Online submission of data available ZLOT Overview -- TLA Conference, April 2002

  13. Moving forward • Describing library technology landscape • You can help: Complete the survey you will receive in the next two weeks • Identifying libraries ready to participate in some of the prototype implementations • You can help: Contact us if you would like your library to be considered • Building interest among vendors and developers to produce prototypes ZLOT Overview -- TLA Conference, April 2002
