Suggests concepts related to information that would be valuable to library users, including the expenses related to information; unique qualities and characteristics of databases; limits of the Web; understanding differences between magazines and scholarly journals; search engine differences; and an appreciation for the amount and variety of…

Discusses information visualization and cocitation analysis and demonstrates the use of an integrative approach to visualizing and tracking the development of competing scientific paradigms. Assumes that a cluster of highly cited and cocited scientific publications in a cocitation network represents the core of a predominant scientific paradigm.…

Zipf's law states that if words in a text are arranged in decreasing order of occurrence, then the product of the rank of a word and the number of times it occurs is a constant of that text. Examination of the probabilities of occurrence of multi-word phrases in information retrieval in relation to the probabilities of occurrence of single words…

Proposes a model, based on a "maximum ranking method," for more simply estimating the frequency of any same-frequency words and identifying the boundary point between high-frequency and low-frequency words in a text. This model was used successfully with English and Chinese texts, demonstrating that the frequency of words and number of…

Term co-occurrence analysis of INSPEC classification codes and thesaurus terms used to index Medical Informatics literature reveals an information science and technology perspective on the field, to accompany the biomedical perspective previously reported. This study continues the search for a better understanding of the structure of Medical…

This review provides a summary of the main theoretical arguments and empirical results available in literature dynamics. Discusses studies of growth, diffusion of information, epidemic theory, and fast-growing literatures. Deals with methodological problems of publication counts, the time factor, and converging indicators, and discusses two…

The most critical challenges that school librarians face are not about finding and organizing resources. The real dillemas lie in working with faculty to plan lessons that take advantage of the resources and tools school libraries have at their disposal, in identifying the skills students need to negotiate new information formats; in anticipating…

The literature on information literacy often assumes that there is an inherent link between the need for information literacy and what is commonly referred to as the information explosion. This assumed link is reflected in programs of information literacy instruction offered by academic libraries. This article argues that the basic concepts of…

This paper investigates the perceptions of the heads of 12 Library and Information Science (LIS) schools on Knowledge Management (KM) education. These heads from North America, Europe and the Pacific region had either been offering KM courses or had an apparent interest in such programs. Data about perceptions were gathered on the nature of their…

The Internet and growth of computer networks have eliminated geographic barriers, creating an environment where education can be brought to a student no matter where that student may be. The success of distance learning programs and the availability of many Web-supported applications and multimedia resources have increased the effectiveness of…

Genetic algorithms (GAs) are a problem solving strategy that uses stochastic search. Since their introduction (Holland, 1975), GAs have proven to be particularly useful for solving problems that are "intractable" using classical methods. The language of genetic algorithms (GAs) is heavily laced with biological metaphors from evolutionary…

This paper presents a comparison of first-level LIS education and training between South Africa and Canada, and based on this comparative description, qualitative identification of similarities and differences are made to highlight strengths and weaknesses in each case. The paper concludes that while similarities exist, the differences stem…

This book has its origins in the deliberations of the international congress on "Education and Informatics; Strengthening International Co-operation," organized in 1989 by the United Nations Educational, Scientific and Cultural Organization (UNESCO) to draw up recommendations to the Director-General of UNESCO and the international…

Maps possess many unique attributes which standard library materials do not, and as a result they are not covered in standard library science courses such as reference, cataloging, collection development, and preservation. Some library schools have responded to this by offering a specialized course in map librarianship. However, few schools offer…

Introduction: Activity theory, developed in the USSR as a Marxist alternative to Western psychology, has been applied widely in educational studies and increasingly in human-computer interaction research. Argument: The key elements of activity theory, Motivation, Goal, Activity, Tools, Object, Outcome, Rules, Community and Division of labour are…
