Abstract

Describes a simple technique that enables students to practice skills in formulating search strategies for electronic databases. Currently used in some library instruction classes at Slippery Roch University, this technique employs cooperative learning and critical thinking skills, requires relatively little time, and is effective with both undergraduates and graduates. In particular this technique claerly demonstrates that information retrieval is greatly affected by the manner in which the question is asked

Abstract

As a result of the Internet, electronic networks occupy a more visible place in everyday life. Until the early nineties, the use of electronic networks was limited to a rather small number of people working in enterprises and universities. Since then, the networks have become more accessible for other citizens. Currently at least 60-70 million people all over the world are estimated to use the Internet (Gaines et al., 1997: 990). In 2000, the number of WWW users alone is expected to reach 160 million (Aldridge & Darwood 1997: 283). The rapid growth of network use has given rise to a lot of research needs. For example, what are the main purposes of network use and to what extent may the Internet replace other channels in information seeking? Thus far, the utilization of networks has been mainly surveyed in the USA but, in recent years issues of use have also attracted increasing attention in Western Europe. This study is a continuation of a research project focusing on the ways in which citizens seek information in the context of everyday life (see Savolainen 1995). An attempt is made to analyze how citizens utilize the electronic networks, primarily for non-work purposes. This paper communicates part of an empirical study; a detailed report is available in Finnish (Savolainen 1998b).

Abstract

An exploratory study was conducted of elementary school children searching a full-text electronic encyclopedia on CD-ROM. 28 third and forth graders and 24 sixth graders conducted 2 assigned searches, one open-ended, the other one closed, after 2 demonstration sessions. Keystrokes captured by the computer and observer notes were used to examine user information-seeking strategies from a mental model perspective. Older searchers were more successful in finding required information, and took less time than younger searchers. No differences in total number of moves were found. Analysis of search patterns showed that novices used a heuristic, highly interactive search strategy. Searchers used sentence and phrase queries, indicating unique mental models for this search system. Most searchers accepted system defaults and used the AND connective in formulating queries. Transition matrix analysis showed that younger searchers generally favoured query refining moves and older searchers fovoured examining title and text moves. Suggestions for system designers were made and future research questions were identified

Abstract

Looks at bibliographic instruction in the age of electronic searching and the the need to provide instruction to insure that remote access to the library is successful. Outlines an approach to teaching library skills by Loomis and Fink in 1993, that is equally relevant to school and public libraries, in which they argue that a successful search can no longer be equated with the quantity of material retrieved but with its relevance. This is dependent upon standardisation of access points, search language and online instructions

Abstract

Research methodologies in several of the social sciences require the use of tests. When assisting social science researchers who seek information on tests, reference librarians do not, themselves, always have direct access to the instruments. Librarians should not only have the knowledge that various print and electronic database resources are available to gain needed information, but they should also have a strategy by which these sources can be searched in an expedient and thorough manner. This paper offers such a search strategy which can be used with the materials commonly found in a large research or specialized test library

Abstract

Reports on a study conducted at Indiana University in the summer of 1993 which observed 10 advanced graduate students in language and literature studies as they conducted literature searches using databases on CD-ROM. Presents a brief review of related literature on relevance judgements, human-computer interaction (HCI) and information seeking behaviour of humanities students. The search strategies of the graduate students under study were found to be typical of humanities scholars, who create large sets and review records quickly to select relevant items. Factors influencing relevance assessments included language, source of publication, author, and length of work. Participants especially appreciated electronic access to the Modern Language Association (MLA) International Bibliography but encountered problems with the controlled vocabulary and analytic entries for books and proceedings. The study has identified problems with database content, presentation and search interfaces which should be considered by system designers

Abstract

School library media specialists do not know which search strategies are most appropriate for the new full-text CD-ROM databases. Reports an experiment conducted to examine the effectiveness of 2 search strategies - analytical and browse strategies - for information seeking and use among high school students using an electronic full-text ancyclopedia for the search task. The experiment sought to determine whether: a short training session in a particular information strategy allows an information seeker to form an adequate mental model of the search task; and a simple 'browse' model compare favourably with a more 'analytical' model for information seeking in a full-text online environment. Both strategies proved effective for finding relevant information yet each demonstrated distinct advantages and disadvantages. Recommends that as new technologies are introduced, school library media specialists should conduct careful observations and controlled comparisons of how students use these systems

Abstract

User studies provide libraries with invaluable insight into their users' information needs and behaviors, allowing them to develop services that correspond to these needs. This insight has become even more important for libraries since the advent of the Internet. The Internet has brought about a development of information technologies and electronic information sources that have had a great impact on both the ways users search for information and the ways libraries manage information. Although humanists represent an important group of users for academic libraries, research studies into their information-seeking behavior since the advent of the Internet have been quite scarce (Ellis & Oldman, 2005) in the past decade. This study presents updated research on a group of humanists, Jewish studies scholars living in Israel, as information users in the digital age based on two categories: (a) the use of formal and informal information channels, and (b) the use of information technologies and their impact on humanistic research.

Abstract

The study reported in this paper is part of a programme of ongoing research based on the model of the Information Search Process (ISP) developed in a series of prior studies by Kuhlthau. This study sought to gain a better understanding of the variety of tasks that involve lawyers as a particular group of information workers, how they use information to accomplish their work, and the role mediators play in their process of information seeking and use. Findings revealed that these lawyers frequently were involved in complex tasks that required a constructive process of interpreting, learning and creating. To accomplish these complex tasks, they preferred printed texts over computer databases primarily because computer databases required well-specified requests and did not offer an option for examining a wide range of information at one time. These lawyers called for an active potential role for mediators in 'just for me' services. 'Just for me' services would encompass designing systems to provide a wider range of access more compatible with the process of construction, applying and developing principles of classification that would offer a more uniform system for organising and accessing files, and providing direction in filtering the overwhelming amount of information available on electronic resources.
