1Moen, W.: Information retrieval protocols : Z39.50 and Search & Retrieve via URL.
In: Encyclopedia of library and information sciences. 3rd ed. Ed.: M.J. Bates. London : Taylor & Francis, 2009. S.xx-xx.
Abstract: Information retrieval (IR) protocols support effective and interoperable intersystem search and retrieval. Although intersystem search methods have been envisioned and under development since the 1970s, it was the Z39.50 IR protocol, first released in 1988, that demonstrated real-world possibilities for such search and retrieval. As the networked information environment changed with the emergence of the World Wide Web, the need for standard IR protocols did not disappear, and one can argue the need is even more compelling given both the visible and invisible Web. A new protocol, based on the experience from Z39.50 but simpler and more comprehensible than Z39.50, is now being used for Web search and retrieval. Search and retrieve via URL (SRU) uses Web technologies and standards resulting in a Web friendly protocol that provides standard search access to existing Z39.50 resources and a wide-range of new non-catalog digital resources. This entry provides both an overview of the two protocols and technical details to understand both. A brief discussion of IR and communications protocols provides background to the specifics of these two IR protocols. Although communication protocols are by their nature technical specifications, this entry focuses on an overview of the functions and capabilities of the protocols. It uses technical concepts and terminology from the protocols to help explain how the protocols work but limits discussion of technical details.

Westport, CT : Mecklermedia, 1994. XIX,516 S.
Abstract: This major study identifies key factors within the library and larger environments that will affect libraries' involvement in national networking policies. It proposes a range of library-related responsibilities and activities to significantly contribute to the overall success of the NREN

Abstract: Academic libraries have been on the leading edge in the provision of services, navigation aids, and user training for the Internet and the emerging National Research and Education Network (NREN). Yet empirical research and synthesis of librarians' experience with electronic networking is scarce. Reports selected findings from a recently completed study that examined the impact of the national networked environment on academic libraries. Its goals was to investigate the roles of academic libraries and librarians in the national networking context. Summarizes the study activities and key issues and findings from data analysis

In: Library and information science research. 15(1993) no.1, S.7-34.
Abstract: The issue of how public libraries will evolve in the Internet/NREN environment remain unanswered. Will the public library survive in this new age? Presents findings from a study that describes and assesses the key issues affecting the role of public libraries in the evolving national electronic networked environment. Recommends roles and strategies for the public library if it is to flourish in the networked environment
