Abstract

As part of the study of human information search strategy, the concept of the search tactic, or move made to futher a search, is introduced. 29 search tactics are named, defined, and discussed in 4 categories: monitoring, file structure, search formulation, and term. Implications of the search tactics for research in search strategy are considered. The search tactics are inteded to be practically useful in information searching. This approach to searching is designed to be general, yet nontrivial; it is applicable to both bibliographic and reference searches and in both manual and on-line systems

Abstract

Problems in determining output size are sometimes associated with the performance of online bibliographic searches for clients in academic and other libraries. These problems are examined through discussion of a fallacy in thinking that arises when searchers try to produce the "perfect thirty-item" online search. Origins of the fallacy are explored by considering sources of misunderstandings between client and searcher and by identifying differences between manual and online searching. Several types of online searches are distinguished, and search techniques that avoid the fallacy are recommended for each search type

Abstract

The Getty Art History Information Program carried out a two-year project to study how advanced humanities scholars operate as end users of online databases. Visiting scholars at the Getty Center for the History of Art and the Humanities in Santa Monica, CA, were offered the oppotunity to do unlimited subsidized searching of DIALOG databases. This second report from the project analyzes how much searching the scholars did, the kinds of search techniques and DIALOG features they used., and their learning curves. Search features studied included commands, Boolean logic, types of vocabulary, and proximity operators. Error rates were calculated, as well as how often the scholars used elementary search formulations and introduced new search features and capabiblities into their searches. The amount of searching done ranged from none at all to dozens of hours. A typical search tended to be simple, using one-word search terms and little or no Boolean logic. Starting with a full day of DIALOG training, the scholars began their search experience at a reasonably high level of competence; in general, they maintained a stable level of competence throughout the early hours of their search experience

Abstract

An information search tactic is a move made to further a search. In this article, 17 "idea tactics" are presented: tactics to help generate new ideas or solutions to problems in information searching. The focus of these tactics is psychological; they are intended to help improve the information specialist's thinking and creative processes in searching. The tactics are applicable to all kinds of situations - both bibliographical and reference searches, and in both manual and on-line systems. Research leads for the study of idea tactics are suggested, and experimental design problems associated with the testing of all sorts of search tactics are discussed

Abstract

The Getty art history information program carried out a two-year project to study how humanities scholars operate as end users of online databases. Visiting scholars at the Getty Center for the History of Art and the Humanities in Santa Monica, California, were offered the opportunity to so unlimited subsidized searching of DIALOG databases. This first report from the project analyzes the vocabulary terms twenty-two scholars used in their natural language descriptions of their information needs and in their online searches. The data were extracted from 165 natural language statements and 1.068 search terms. Vocabulary categories used by humanities scholars were found to differ markedly from those used in the sciences, a fact that imposes distinctive demands on thesaurus development and the design of online information systems. Humanities scholars searched for far more named individuals, geographical terms, chronological terms, and discipline terms than was the case in a comparative science sample. The analysis provides substantial support for the growing perception that information needs of humanities scholars are distinct from those of scholars in other fields, and that the design of information-providing systems for these scholars must take their unique qualitites into account

Abstract

Throughout most of human history, people got the information they needed for their lives more or less automatically and unthinkingly--through people they talked with, and from their own life experiences. Today, we are inundated with information but often know little about how to find our way through the vast sea of recorded knowledge to get to what we really want and need. In the information sciences researchers have thought a great deal about information seeking, and have studied people in the grip of trying to satisfy an information need. Much has been learned about how to enable comfortable and fun information searching in human, paper, and digital environments. Professor Marcia Bates of UCLA's Department of Information Studies has collected fifteen of her major papers on information searching in theory and practice in this volume. The articles address many aspects of searching for information, including searching tactics and techniques, the "vocabulary problem" in online searching, the kinds of indexing terms to use in various contexts, the Bradford Distribution and its effects on searching in large databases, the true nature of browsing, and how to design computer interfaces for successful searching. For all the variety in types of information systems, the human being interacting with an information source is remarkably stable in psychology and behavior. These human traits and system features are explored in depth in this book. Bates' popular articles, "What is Browsing--Really?" and "The Design of Browsing and Berrypicking Techniques for the Online Search Interface," are included. This is Volume II of three containing selected works by Bates. The others are titled: Information and the Information Professions (Vol. I) and Information Users and Information System Design (Vol. III)

Abstract

Young undergraduate college students are often described as "digital natives," presumed to prefer living and working in completely digital information environments. In reality, their world is part-paper/part-digital, in constant transition among successive forms of digital storage and communication devices. Studying for a degree is the daily work of these young people, and effective management of paper and digital academic materials and resources contributes crucially to their success in life. Students must also constantly manage their work against deadlines to meet their course and university requirements. This study, following the "Personal Information Management" (PIM) paradigm, examines student academic information management under these various constraints and pressures. A total of 41 18- to 22-year-old students were interviewed and observed regarding the content, structure, and uses of their immediate working environment within their dormitory rooms. Students exhibited remarkable creativity and variety in the mixture of automated and manual resources and devices used to support their academic work. The demands of a yearlong procession of assignments, papers, projects, and examinations increase the importance of time management activities and influence much of their behavior. Results provide insights on student use of various kinds of information technology and their overall planning and management of information associated with their studies.
