Geographic information system (GIS) technology is a rapidly growing and powerful method for managing and analyzing spatial data and information for libraries. This article introduces GIS basic concepts, reviews GIS usage in libraries, and presents some challenges, strengths, and opportunities for libraries and GIS. Six figures illustrate the…

Reports on two experiments comparing the adequacy of naturalistic procedures in emotion-display research with standard procedures. The first experiment explored samples of naturally-occurring emotional speech with free-choice emotion labels, and later with labels from a standard set. The second compared valency ratings of words presented…

Academic clientele expect their library to select the best information and organize it effectively for their personal consumption. Some answers to a hierarchical approach are customization through a MyLibrary feature, a role-based vertical view, and a powerful search engine all built on a rich resource database. Each is discussed. (AEF)

The resolution power of a key is its ability, in the context of other keys for a given request, to increase query performance. This article studies the statistical properties of search keys, methods of characterizing the resolution power of keys automatically, and effects keys of varying resolution power have on retrieval effectiveness. (AEF)

Discusses database usage data from a sample of 98 public libraries and library systems in the United States and Canada that revealed patterns of use. Results of the questionnaire used, which is appended, showed the number of workstations was statistically correlated with amount of use. (Author/LRW)

Describes the University of California at Berkeley's participation in the TREC (Text Retrieval Conference) interactive track experiments. Highlights include results of searches on two systems, Cheshire II and ZPRISE; system design goals and implementation; precision and recall results; search questions by topic and system; and results of…

Examines a source of linguistic data--newspapers--and discusses related problems of text-type classification and feature interpretation. Using texts from East Africa as a database, the article assesses the influence of different production contexts on the text composition and analyzes the samples for the multifunctional variable of…

Describes online and CD-ROM databases that contain trademark information and presents guidelines for using these sources to help research and create trademarks. Sidebars present Internet trademark resources, searching tips, additional print and online sources for trademark information, U.S. Federal trademark databases, and online access to…

Proposes a new technique for teaching search strategies on CD-ROM databases, using common novice errors to illustrate basic search techniques. By incorporating examples of search errors, such as use of search terms that are too narrow or broad, or failure to utilize thesaurus terms, database users may more readily comprehend why searches are…

An empirical investigation of information retrieval using the MEDLINE database was carried out to study user behavior, performance and to investigate the reasons for suboptimal searches. Subjects were two groups of final year medical students (novice and expert users of the search system). Findings indicate that just one factor can cause poor…

It is difficult to incorporate long term studies such as ecology into classroom settings. Discusses how to reach and download research center data available on the web. Recommends Long Term Ecological Research (LTER) sites for downloading and interpreting data. Explains the downloading procedure using a Netscape browser, and uses Excel and Lotus…

Explains desktop metasearch engines, which search the databases of several search engines simultaneously. Reviews two particular versions, the Copernic 2001 Pro and the BullsEye Pro 3, comparing costs, subject categories, display capabilities, and layout for presenting results. (LRW)

A public university developed a comprehensive data file with specifically selected information from students' records in the admissions, registrar's, and student financial aid offices. Data analysis revealed some enrollment trends of first-year, direct-from-high-school applicants related to financial aid variables. (EV)

Presents a model of some of the typical important layers in the design of information systems, and shows how those layers interact in operation. Suggests that these layers are in the way of a cascade of each layer affecting the next. Presents a model of this cascade of interactions in information systems. Provides examples from networked…
