- Abstract
- This article will examine the Z39.50 Information Retrieval protocol. It will look at some of the history of the protocol, its operation, and some of the major projects that have made use of it. There has been enough written (perhaps too much) about Z39.50 in the last several years so it is not intended to be a tutorial or detailed description of the protocol. The material that will be presented will try and put some context around the discussion. For those readers who are interested in delving into Z39.50 in a more technical manner, references to much of the material that has been written about it over the years will be provided at the end. Finally, the article will conclude with some thoughts on how technology and technological infrastructure have changed in the years since Z39.50 was initially developed and deployed, and where the protocol has so far lived up to its goals, and where it has perhaps failed to meet some of the high expectations that at least some people involved in the Z39.50 community held for it. The article will conclude with some of the author's speculations (and they are really no more than that) of what the future role of Z39.50 is likely to be.

- Abstract
- The focus of this study is the search behavior of remote users of the University of California MELVYL Library System, an OPAC. Transaction logs from randomly selected remote user search sessions are analyzed. Descriptive data on the number and type of searches, choice of search mode and database, number of retrievals, number and type of errors, and use of system HELP facilities are presented. The search data have been cross-tabulated with demographic data on the same group of remote users, collected through an online survey conducted by the authors. Effectiveness of system usage is discussed. A case mode is made for the desirability of additional heuristics in the catalog portion of the system

- Abstract
- The rapid growth of the Internet TCP/IP networks has encouraged the deployment of management products based on the Internet's Simple Network Management Protocol (SNMP). However, many organizations, including most telecommunications service providers, continue to define enterprise management solutions based on ISO/CCITT standard management and underlying Common Management Information Protocol (CMIP). Concludes that the key to achieving timely, effective, integrated management is to encourage a transition process aimed away from existing commercial investment in both ISO/CCITT and Internet based management technologies through deployment of common methods and tools which support integration
