This focus group study explored library patrons' opinions about Texas A&M library's Web pages. Discusses information seeking behavior which indicated that patrons are confused when trying to navigate the Public Access Menu and suggests the need for a more intuitive interface. (Author/LRW)

Proposes four design principles of an information access system that link information sources regardless of implementation medium, information structure, or interface style. Provides examples from an undergraduate course in information science at the University of California at Los Angeles. (Author/AEF)

Examines argumentative and research papers written by students using Macintoshes in comparison to those written using IBM-compatibles. Finds that differences are not large enough to justify claims that the use of a graphical user interface affects writing skills. Suggests that rapid changes in technology makes the issue moot. (RS)

Discussion of usability testing of Web interfaces for virtual libraries focuses on a usability study conducted at the University of South Florida. Highlights include testing instruments; discrepancies between actual performance and perceived performance; and the need to use plainer language and less jargon. (LRW)

Describes the National ADC0804, an inexpensive and readily available integrated ADC converter that can convert an analog voltage to an 8-bit signal. Includes schematic drawings. (DDR)

Provides ideas and outcomes for nine computer laboratory experiments using a commercial eight-bit analog to digital (ADC) interface. Experiments cover statistics; rotation; harmonic motion; voltage, current, and resistance; ADC conversions; temperature measurement; single slit diffraction; and radioactive decay. Includes necessary schematics. (MVL)

Describes the design, implementation, and evaluation of a distributed Web-based learning community (DisWBLC) based on knowledge sharing for college students. Highlights include virtual learning communities; Web site resource searching; databases; screen design; user interface; feedback from teachers and students; and future possibilities.…

Contained in this issue are 30 articles reviewing advances in different fields of analytical chemistry since 1980. Cumulatively, these reviews list over 1000 references. (CW)

Using a computerized logic course employing the Carnegie Mellon Proof Tutor problem-solving environment, crucial features of computer environments were isolated and relative pedagogical effectiveness was assessed. Students used computerized environments to construct proofs and were presented with identical course materials on sentential logic. The…

Reviews technological innovations that have allowed the emergence of digital libraries and fostered new multidisciplinary collaborations; identifies areas of collaboration between librarians and engineers; and gives examples from digital spatial library projects funded by the National Science Foundation that involve maps, cataloging, data…

Describes a simple circuit based on an inexpensive quad operational amplifier that permits a direct-reading temperature instrument to be constructed using silicon diodes. Encourages the use of this equipment in introductory thermal experiments. (DDR)

University portals provide a new computerized interface between colleges and constituent groups. This article discusses: campus portals and possible features they may contain, nine strategies for portal projects, collaborative mechanisms to develop and implement portal projects, criteria for determination of campus portal readiness, potential…

Discusses the need for an intuitive library information gateway to meet users' information needs and describes the process involved in redesigning a library Web site based on experiences at Roger Williams University. Explains usability testing methods that were used to discover how users were interacting with the Web site interface. (Author/LRW)

Client/server computing and the adoption of the World Wide Web make it possible for academic libraries to build automated library systems that present locally mounted and remote resources through a common interface. This article recounts issues encountered by the Iowa State University Library as it undertook this process. (Author/LRW)

Classifies sites on the World Wide Web according to purpose. Examines what metaphorical design has to offer Web site designers and details how principles of metaphorical design were applied to create a university Web site. Discusses technological limitations that influence design decisions and when metaphorical design might not suit a Web site.…
