    Abstract
    Compares and contrasts online searching on DataStar using the 'classic' command language, with access via the more recent Web interface (DataStar Web). The search functionality of the 2 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

    Abstract
    Reports progress and future plans for a project to study the interactions of users with information retrieval interfaces. Tests are run with professional data base searchers and with end users who are members of a profession but have little or no searching experience. Interfaces tested include a command language search system used to search DIALOG bibliographic data bases, a non-procedural system that produces DIALOG commands, and several full text systems, including one using hypertext. The intent is to determine which kinds of users perform best with each type of interface. The project is being conducted jointly bay the University of Toronto and the University of Maryland

    Abstract
    Reviews STN Easy, a Web service that provides access to 2 dozen leading sci-tech databases which is produced jointly by the Chemical Abstracts Service of the American Chemical Society, Germany's FIZ-Karlsruhe, and Japan' SCience and Technology Corporation. It employs a graphical interface, relevance searching, and output based pricing. STN Easy is STN's solution for members of the technical community and others who are not users of the main STN service. The databases included the leading files in STN's major subject areas namely: SCISEARCH; Mathematics Abstracts; MEDLINE; EMBASE; BIOSIS; COMPENDEX; INSPEC; Worlds Patent Index; Inpadoc; US Patents Fulltext; PROMPT; and Chemical & Engineering News. Discusses searching; pricing; and the pros and cons of end user searching

    Abstract
    STN Easy is a new graphic user interface for the WWW access to over 20 major online databases in business, science, technology and patents. Patent information is available from a number of Web sites but argues that STN Easy offers extensive coverage combined with both searching sophistication and operational simplicity. Concludes that STN Easy is not a replacement for nor competitor to STN, but provides a complementary means of retrieving patent information for end users or others who do not need the full power of a command language
