Eleven articles introduce expert systems applications in library and information science, and present design and implementation issues of system development for reference services. Topics covered include knowledge based systems, prototype development, the use of artificial intelligence to remedy current system inadequacies, and an expert system to…

Summarizes four options for libraries that want to offer end user searching: end user systems (Bibliographic Retrieval Service's Afterdark, DIALOG's Knowledge Index); front-end microcomputer software (Sci-Mate Searcher, Pro-Search, WILSEARCH); gateway services (EASYNET); and local databases (now available on floppy and compact discs). Advantages…

Presents the background, database, user instructions, design criteria, hardware, and commands of the online catalog system at the University of New Brunswick (Canada) library, as well as self-instructional features of the system.
