Virtual and non‐virtual realities: the changing roles of libraries and librarians

What is the future for libraries and their librarians? In trying to give an answer to this pressing question we do not deal with utopian libraries of the next century, but with the library and the librarian of the next decade. The emphasis is on libraries within educational and research institutions, especially university libraries. We examine the changes confronting the library of the future and identify four key aspects of the library of the future. It will be (i) a gateway to information, whatever format this information comes in and wherever it is located; (ii) an expertise centre; (iii) a physical entity, not only in the sense of being a social meeting place and place of scholarly interaction, but also as a place where students and other users are provided with modern study facilities and adequate user support; and (iv) a collection centre of printed material. Such libraries can only take on an appropriate shape and will only survive if the institutions that librarians serve in meet the four criteria outlined above. We look at the demands that will be made on professional library knowledge and skills and the new job responsibilities and job attitudes required.

The new social studies,textbooks, and reform in social studies

The New Social Studies curriculum development movement was short-lived, in part because project staff were not sensitive to the realities of the educational context within which their materials and methods would be used. Although textbook-based recitation persists in social studies classrooms, textbooks are not a ready mechanism for reform. Among the reasons are the institutional constraints on publishers and the difficulty in effecting curricular change without appropriate teacher preparation and modifications in the educational environment. James P. Shaver id professor of secondary education, associate dean for research, College of Education, and acting dean of the School of Graduate Studies, Utah State University, Logan. He has been president of the National Council for the Social Studies and has received NCSS’s Citation for Exemplary Research. His numerous books and articles include materials for students, research reports, and discussion of educational rationale-building, rationales for social studies education, and research philosophy.     

Chaos theory, informational needs, and natural disasters

This study applies chaos theory to a system-wide analysis of crisis communication in a natural disaster. Specifically, we analyze crisis communication during the 1997 Red River Valley flood in Minnesota and North Dakota. This flood, among the worst in modern American history, consumed entire metropolitan areas, displacing thousands of people. The conditions and decisions leading to the disaster, and the subsequent reactions are retraced. Communication related to river crest predictions (fractals), the shock at the magnitude of the crisis (cosmology episode), novel forms of reorganizing (self-organization), and agencies that aided in establishing a renewed order (strange attractors) are evaluated. Ultimately, we argue that preexisting sensemaking structures favoring rationalized, traditional views of a complex system led officials to make inappropriately unequivocal predictions and ultimately diminished the effectiveness of the region's crisis communication and planning.
