- Abstract
- This report presents the results of a survey of users who access the University of California's online union catalog, the MELVYL library system, via microcomputers with modems or connections carried through local or wide area networks. The report includes descriptive statistics on user location, status, subject interest, affiliation, in-library versus out-of-library usage patterns, need for assistance, and desire for new features

- Abstract
- CD-ROM databases are finding a permanent niche in libraries and librarians are trained both to use each new product and to keep abreast of changes in them. From the library user point of view it is possible to dial into or remotely access CD-ROM databases. Discusses the use of the communications software pcAnywhere, examines the benefits to users and libraries of remote access, and lists other areas which might be of interest to learning resource centres in regard to CD-ROM services

- Abstract
- The ANSI Z39.50 standard was adopted 10 years ago. It outlines a set of rules and procedures to allow a computer system to search the databases provided by another system and to retrieve the results of that search. Traces its development adoption in library automation product lines. Recent major developments have been the migration to version 3 and the adoption of community profiles. Community profiles are documents that describe agreements that a community of interest develops to ensure clients and servers can interpret in specific ways. Describes the Government Information Locators Service, WAIS, ATS, ZDSR, Cataloguing, CEOS CIP, Digital Collection, Digital Library Objects and Museum Profiles

- Abstract
- This study aimed to determine if the searching behaviour of remote users of LIAS, Penn State's online catalogue differed from those using the OPAC within the library. More than 1.000 searches done by remote users (those accessing the system via either dial-access or the university's computer network) were compared to more than 1.000 searches done by in-house users. Each search was duplicated step by step and analysed according to a pre-determined set of criteria. Although few dramatic differences were found between the 2 groups, there were enough subtle differences to generate interest. In general, remote users are the more sophisticated searchers, bearing out the assumption that remote users seem to have a better conceptual knowledge of how an information system should operate. On the other hand, they struggle more with the procedural details of how to use the OPAC. Dial-access users seem to constitute a unique group of users: their searches are often quite different than those done by either network or in-house users

- Abstract
- The Z39.50 standard for information retrieval is important from a number of perspectives. While still not widely known within the computer networking community, it is a mature standard that represents the culmination of two decades of thinking and debate about how information retrieval functions can be modeled, standardized, and implemented in a distributed systems environment. And - importantly -- it has been tested through substantial deployment experience. Z39.50 is one of the few examples we have to date of a protocol that actually goes beyond codifying mechanism and moves into the area of standardizing shared semantic knowledge. The extent to which this should be a goal of the protocol has been an ongoing source of controversy and tension within the developer community, and differing views on this issue can be seen both in the standard itself and the way that it is used in practice. Given the growing emphasis on issues such as "semantic interoperability" as part of the research agenda for digital libraries (see Clifford A. Lynch and Hector Garcia-Molina. Interoperability, Scaling, and the Digital Libraries Research Agenda, Report on the May 18-19, 1995 IITA Libraries Workshop, <http://www- diglib.stanford.edu/diglib/pub/reports/iita-dlw/main.html>), the insights gained by the Z39.50 community into the complex interactions among various definitions of semantics and interoperability are particularly relevant. The development process for the Z39.50 standard is also of interest in its own right. Its history, dating back to the 1970s, spans a period that saw the eclipse of formal standards-making agencies by groups such as the Internet Engineering Task Force (IETF) and informal standards development consortia. Moreover, in order to achieve meaningful implementation, Z39.50 had to move beyond its origins in the OSI debacle of the 1980s. Z39.50 has also been, to some extent, a victim of its own success -- or at least promise. Recent versions of the standard are highly extensible, and the consensus process of standards development has made it hospitable to an ever-growing set of new communities and requirements. As this process of extension has proceeded, it has become ever less clear what the appropriate scope and boundaries of the protocol should be, and what expectations one should have of practical interoperability among implementations of the standard. Z39.50 thus offers an excellent case study of the problems involved in managing the evolution of a standard over time. It may well offer useful lessons for the future of other standards such as HTTP and HTML, which seem to be facing some of the same issues.
