Abstract
This paper compares and contrasts online searching on DataStar, a major European host now owned by The Dialog Corporation, using the “Classic” command language, with access via the more recent Web interface. DataStar, established in 1981, was one of the first online hosts to offer a web interface, in December 1996. DataStar Web was upgraded in December 1997. “Classic” DataStar command line searching requires familiarity with commands, operators, database labels, etc. DataStar Web offers searching via apparently simple steps: eg. selecting a database, entering search terms. The functionality of the two interfaces is considered, looking in turn at entering the system, selecting a database, searching, output and display, terminating the search session, error messages and help pages, and support, training and documentation. The search functionality of the two interfaces is not identical, although both use the same retrieval software and access the same databases. Many of the differences affect retrieval effectiveness and may trip up novice and experienced searchers alike.
