A number of tests were conducted using a variety of fields, terms, and parameters, and examples of results are provided. The authors' findings are…

Applies a prefix trie index, or trie hashing, to the problem of providing fast search times, fast load times, and fast update properties in a bibliographic or full-text retrieval system with inverted files. Statistics are given for a test database consisting of an online catalog at the University of Western Ontario. (Author/LRW)

Assesses the current state of reference structures in online public access catalogs (OPACs) in a framework defined by stagnation, progress, and future challenges. Outlines six areas for reference structure development. Twenty figures provide illustrations. (AEF)

This paper provides the documentation for the program that provides access to the University of Illinois Online Catalog (OLC), together with a script to be used with 17 slides explaining the development of the program. Advantages of connecting a database to a computer-assisted instruction (CAI) system are outlined and sources of additional…
