An online demonstration, designed to enhance comprehension of Sternberg's (1966) short-term memory scanning task, involved rapidly searching under virtual cups for a ball. We randomly assigned students to 1 of 3 groups, all of whom read the same textbook description of Sternberg's work: A demonstration group used 3 search methods to look for balls…

Discusses file transfer protocol (FTP) servers for downloading archives (files with particular file extensions), and the change to HTTP (Hypertext transfer protocol) with increased Web use. Topics include the Archie server; proxy cache servers; and how to improve the hit rate of archives by a combination of caching and better searching mechanisms.…

Describes strategies that can be used to search the DIALOG database by date to add precision to searching. The "Current" command is explained, as well as other commands; ways to search a specific year are described; and DIALOG files that are already restricted by date are discussed. (LRW)

Describes a computer program that manages a collection of pictures such as photographic slides, overheads, or computer images in one or more databases. Discusses organizing the database, searching, and keeping track of the time needed to present the images. (Author/LRW)

Discusses the use of Boolean logic in information-retrieval systems and analyzes existing criticisms of operational systems. Considers users' ability to use and understand Boolean operators, ranking, the quality of query formulations, and negative effects of criticism; and concludes that criticism is directed at the methodology employed in…

Discussion of the growth of institutional image collections focuses on the development of a visual thesaurus to provide access to the photographic archive of the National Aeronautics and Space Administration (NASA). Addresses specific access problems, including the accurate and rapid description of images entering collections, and searching…

Because a comprehensive or balanced collection of information may not be necessary or desirable, deciding why information is needed is an integral step in focusing a search strategy and information analysis. This article discusses information needs, barriers to comprehensiveness, search strategies (primary and secondary sources), and variables and…

Discusses the role of search engines in Web usability and analyzes and evaluates the retrieval effectiveness of various indexing and searching strategies on a new Web text collection. Highlights include preprocessing techniques that might improve retrieval effectiveness; and hyperlinks as useful sources of evidence in improving retrieval…

Discusses the search option on Web sites and explains how to develop a search engine. Highlights include search options, including Boolean operators, graphical interface, and language; platform and server compatibility; indexing; metadata; XML; customization options; installation and configuration; evaluation; usability; and cost.

Highlights include motivations; numerous examples; word-based and char-based searches; tag-dependent full-text searches; text normalization; query algebra; data models and term language;…

Investigates problems of using commercial search engines for Web-based research. Findings indicate that search engines are highly variable in their results, are limited in the search functions they offer, have poorly and/or incorrectly documented functions, use search logics that are opaque, and change search functions they offer over time.…

Discussion of citation analysis on the Web considers Web hyperlinks as a source to analyze citations. Topics include basic graph theory applied to Web pages, including matrices, linear algebra, and Web topology; and hubs and authorities, including a search technique called HITS (Hyperlink Induced Topic Search).
