Compares and evaluates the differences between OCLC's dial-up and World Wide Web FirstSearch access methods and their interfaces with the underlying databases. Also examines NetFirst, OCLC's new Internet catalog, the only Internet tracking database from a "traditional" database service. (Author/PEN)

With the advent of CD-ROMs, libraries began to limit online searching via DIALOG. To increase DIALOG's market share, Colorado Alliance of Research Libraries (CARL) Corporation is developing graphical user interfaces using World Wide Web and Windows technology and has reached agreements with Knight Ridder Information and with most of their database…

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)

Based on the results of a two-year study conducted by the Getty Art History Information Program of online searching by humanities scholars, implications are drawn for the design of information products. Topics include characteristics of humanities scholars; design and content of databases; indexing vocabulary; and interfaces and command languages.…

In 1996, the Colorado Library Resource Sharing and Information Access Board initiated a project to explore a patron-initiated interlibrary loan (ILL) system utilizing the ACLIN (Access Colorado Library Information Network) infrastructure and interfacing with local catalogs, remote databases, and bibliographic utilities. This report summarizes the…

Describes push technology as a new type of selective dissemination via the Internet and discusses filtering, channels of information, Web browser interfaces, data transfer, the role of databases, and database technology. A list of companies that provide push technology is included. (LRW)

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.…

Describes "Placemark," an online tool for creating and managing Web pages within a school or district Web site. Topics include interviews with teachers to determine their needs, which centered around creating instructional materials and activities; online newsletters for parents; feedback to test the interface; formative evaluation; and…

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)

Described is a physical pendulum experiment with variable pivot as an example of maximizing computer benefits in laboratory interfacing. The laboratory procedures using spreadsheet graphics package are discussed. A diagram of the pendulum, basic formulas, and theoretical curve is provided. (YP)

Described is a position transducer used to convert the position of an object into a voltage read by a computer with use of an interface board. The arrangement of the apparatus, electronic circuit, and typical graph displays are presented. Discussed is the instructional use of the transducer. (YP)

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…

A study for assessing automatic vocabulary switching from a thesaurus to Library of Congress Subject Headings (LCSH) revealed that a maximum 61%, but a more realistic 41.5%, of the terms could be switched automatically; as long as LCSH is used for subject descriptions in online catalogs, interfaces for vocabulary switching can only be partially…

Presents a distillation experiment that uses temperature sensors connected to a computer in place of thermometers, and enables the whole class to view the data on a monitor and interpret and discuss the data in real time. (JRH)
