This paper examines representative research in information science and compares its designs to an abstract ideal of the experimental research design. Threats to validity of conclusions are highlighted, including history, maturation, testing, instrumentation, statistical regression, selection biases, experimental mortality, and selection-maturation…

Four empirical laws of bibliometrics--anomalous number, Lotka's, Zipf's, and Bradford's--together with Laplace's "law of succession" and de Solla Price's cumulative advantage distribution are shown to be almost identical. A simple model shows that the frequency forms conform with inverse square law over appropriate interval. (Fifteen…

Proposes scientific theory of the subject matter of library and information science and how it can be organized in terms of the function of documents and their basic use. A hierarchy of classes of documents is described including one, several, or all of the following: information, creativity, understanding, and explanation. (Author/EM)

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…

Delineates various levels of theory with implications for research in library and information science. Based upon a review of literature on theory building and research methods in the social sciences, a model is proposed which displays a taxonomy of theory in hierarchical form. (EM)

Designed to minimize information overload in telecommunications systems, the formal model developed in this paper predicts the usefulness of a message based on the available message features, and may be used to rank messages by expected importance or economic worth. The assumptions of binary and two Poisson independent probabilistic distributions…

Traces emergence and development of research in library science; argues that prevailing ideology posits desirability of adoption of a positivist epistemology for research in the field; and proposes drawing of work in critical theory and hermeneutics, to rethink the epistemological foundations of research in library and information science. (38…

Reviews different structures and techniques of knowledge representation: structure of database records and files, data structures in computer programming, syntatic and semantic structure of natural language, knowledge representation in artificial intelligence, and models of human memory. A prototype expert system that makes use of some of these…

Examines the literature on the myth of "hard science-soft science" as a means of defining scientific specialties and classifying science literature, and discusses some shortcomings of scholarship in library and information science. Use of Toulmin's categorization of sciences to organize the literature and provide access for scientists is…

Educational dissemination has contributed a number of innovative concepts and strategies to information science. Much-misunderstood ERIC, which combines research reports with policy documents and teaching materials, is one of the first and best examples of a field-oriented rather than discipline-oriented database. Building on ERIC, federal…

Develops a framework for analyzing the value of information, information products, and services from the viewpoint of information use, and analyzes the practical values of different types of information to study the problems involved in assessing their value-in-use and exchange value. Existing research studies are analyzed using this approach.…

Focuses on the benefits of model care curriculum development in computer-based information systems relevant to the needs of developing countries. Suggested procedures include outlining search rationale, examining existing curricula in developed nations, evaluating such education in Kuwait, presenting a model curriculum, comparing it with relevant…

Developed to guide the research of the Educational Technology Center, a consortium based at Harvard Graduate School of Education, this report addresses the use of new information technologies to enrich, extend, and transform current instructional practice in science, mathematics, and computer education. A discussion of the basic elements required…

The Fourth International Research Forum in Information Science (IRFIS 4) focused on two themes: user-oriented research in information science and experimental and practical investigations of the mediation and use of information. An opening speech by Bjorn Tell reviewed information research policy in the United States, France, England, Japan, the…
