Two tables compare projected costs of online versus offline retrieval of citations from 50 databases using BRS and DIALOG. Data include database; databank; cost of access per hour; cost of 15-minute search with no retrieval; and cost of 15-minute search plus cost of 10 and 30 online or offline citations. (CLB)

Identifies five design requirements for electronic encyclopedias, based on the content and structure of printed encyclopedias and the uses that people make of them. Three existing hypertext programs (Owl International's Guide, HyperCard, and HyperTIES) are compared in terms of their ability to satisfy these design requirements. (CLB)

The performances of students in grades two-three and grades four-six in using an online encyclopedia are compared, examples of searches are presented, and suggestions for further research are…

Discussion of the cost effectiveness of searching online versus searching on CD-ROM highlights an example that compares costs for searching the ERIC database. Fixed costs and variable costs are described, labor costs are examined, implications for management are considered, and the effect of the number of databases and workstations is discussed.…

Describes experiments in Arabic information retrieval using 29 queries against a base of 355 bibliographic records. Using roots and stems as index terms worked better than words, and the root performed as well as or better than the stem at low recall levels and definitely better at high recall levels.
