This continuation of an earlier article discusses online vendors' responses to users' concerns as well as the future of online services. Maxwell Online, Dialog, Mead Data, Data-Star, and Dow Jones News/Retrieval address user needs, search strategies, databases, document retrieval and display, user interface, and cost and economic issues.

This study investigated the usefulness of end user systems to library and information science students. Seventeen volunteers were offered free searching on BRS/After Dark and DIALOG's Knowledge Index. The search itself, postsearch questionnaire, and completed research papers were analyzed for databases used, cost and time online, and precision.…

Highlights the changes that have occurred from 1987-93 in database access systems. Topics addressed include types of databases, including CD-ROMs; enduser interface; database selection; database access management, including library instruction and use of primary literature; economic issues; database users; the search process; and improving…

Describes a study that investigated the effects of cognitive style (field dependent and field independent) and online database search experience (novice and experienced) on undergraduate World Wide Web search performance. Considers user factors to predict search efficiency and discusses implications for Web interface design and user training…

This paper promotes further discussion and analysis of interactivity in learning environments and contains a classification of interaction types appropriate for consideration in multimedia settings. Through an examination of related factors associated with navigation and control, a matrix of interactive dimensions is proposed. (Author)

This study reports and compares patron usage rates from January 1987 to May 1988 for three separate ERIC database systems at the library at Texas Woman's University (TWU): (1) online searches of the ERIC file through the mainframe computers of DIALOG Information Services (DIALOG ERIC), which are offered in the library reference department by…

Describes software for displaying documents on computer graphics screens which provide the opportunity for interactive user interfaces. Based on a software system called Guide, this new approach relies on advances in hardware, such as the CD ROM, and can be used in the front end of a document retrieval system. (Author/LRW)

Examines the educational potential for intelligent agents as cognitive tools. Discusses the role of intelligent agents: managing large amounts of information (information overload), serving as a pedagogical expert, and creating programming environments for the learner. (AEF)

This report describes a three-stage catalog use study conducted at the University of Wisconsin-Stout from 1982 through 1986 to determine the types of searches conducted and search success rates for both the card and online catalogs during the library's transition to the DataPhase Automated Library Information System (ALIS). Phase I, conducted…

Online searching is a complex problem solving task requiring the searcher to combine multiple sets into Boolean expressions. Since spatial ability has been correlated with problem solving tasks which involve abstract conceptual associations, this report argues that it is a significant factor in the information user's ability to both comprehend and…

This composite report provides summaries of presentations by 10 experts at the 23rd Annual Clinic on Library Applications of Data Processing in April 1986 at the University of Illinois at Urbana-Champaign. All were concerned with the design of online systems to make them easier for library patrons to use. (Author/CDD)

Describes a specialist bibliographic database of literature in the field of artificial intelligence created by the Turing Institute (Glasgow, Scotland) using the BRS/Search information retrieval software. The subscription method for end-users--i.e., annual fee entitles user to unlimited access to database, document provision, and printed awareness…

Describes the design of a prototype adaptive online catalog that was implemented as a transparent workstation-based front end system to MELVYL, the online catalog for the University of California libraries. Problems with searching bibliographic retrieval systems are reviewed, including irrelevant retrievals and the inexperience of most users.…

Discussion of search strategy formulation focuses on a study at the University of North Carolina at Chapel Hill that analyzed how medical students developed and revised search strategies for microbiology database searches. Implications for future research on search behavior, for system interface design, and for end user training are suggested. (16…

This report presents the objectives, methodology, and results of a study which assessed the selection and utilization of four MEDLINE search systems by faculty and medical residents at the George Washington University Medical Center. The four systems, which were provided or sponsored by the Himmelfarb Health Sciences Library, offer a wide range of…
