Shows how hierarchical goal decomposition can be used to understand the knowledge that is required to perform information search tasks. Pinpoints strategies that are known by expert searchers; why such knowledge is difficult for novices; and how the analysis provides testable predictions of behavior based on the acquisition of different types of…

Describes search tactics useful for online searching and how to use them, and identifies the points in a search at which they are most useful. An extended example shows how all the tactics may be used in an online search. (EM)

Sixty-one students provided the Library of Congress (LC) subject terms they would use to search an academic library catalog in 30 hypothetical searches. Students had difficulty developing strategies. The study concluded that LC subject cataloging needs rationalization. (KP)

Seventeen idea tactics to aid information specialists in furthering a reference search are defined as parts of total search strategies, and are grouped into idea generation and pattern breaking modes. Problems in testing such tactics are discussed. (FM)

Explains seven types of subject descriptions commonly used in databases--hierarchical classification, category codes, subject headings, descriptors, faceted classification, post-controlled vocabulary, and natural language--and describes specific search techniques for taking advantage of the strengths of particular types of vocabularies. An overall…

Without spending any more time or energy compiling the bibliography, by simply making the specifications of our search available to the user, we would have greatly improved the instrument's utility and effectiveness for the user's search. (Author)

As part of the study of human information search strategy the concept of the search tactic, or move made to further a search, is introduced. Twenty-nine tactics are named, defined, and discussed, and implications of search tactics for research in search strategy are considered. (Author/MBR)

Examines several points in the cycle of publication of scientific research results--informal presentations, conference presentations, technical report literature, journal articles, abstracts, scientific reviews, treatises, textbooks--and recommends search strategies for locating needed references in a library. Eight references are listed. (EJS)

Examines various ways of dividing the labor of an information search between the person and the system. Different configurations of two dimensions--degree of system involvement in searching and types of search activity carried out by the person or system--are discussed. Recommendations for further research and development are offered. (49…

This report on the Getty Online Searching Project, which studied the end-user searching behavior of 27 humanities scholars over a 2-year period, focuses on previous familiarity with retrieved documents. Topics include document familiarity and relevance; document familiarity and information retrieval; measuring retrieval success; and document…

Discusses indexing and access to digital resources, especially on the Internet. Topics include subject searching versus indexing; multiple terms of access; folk classification; basic level terms; folk access; Bradford's Law; Zipfian distributions; vocabulary scalability; the Resnikoff-Dolby 30:1 Rule; domain-specific indexing; and implications for…

The Getty Information Institute conducted a two-year study of online searching by 27 humanities scholars using DIALOG. Discusses results and recommends that library services: provide interdisciplinary information for humanities scholars; recognize that online searching in humanities may be harder than in sciences; expect wide preferences for…

Reports a study that analyzed natural language search statements constructed by 22 Getty Visiting Scholars as they researched humanities topics on DIALOG. Results show a greater use of names, geographical areas, chronological periods, and discipline terms than scientists use, with implications for the design of humanities online systems and…

The SNAPdragon (School Network Action Project) project investigated how elementary school children interact with the Internet by asking them to build an annotated directory of World Wide Web sites for other children. Describes instructional arrangements and development of searching skills; and discusses critical thinking skills and interschool…
