Abstract
This essay is a personal analysis of information science
as a field of scientific inquiry and professional practice
that has evolved over the past half-century. Various sec-
tions examine the origin of information science in re-
spect to the problems of information explosion; the so-
cial role of the field; the nature of “information” in infor-
mation science; the structure of the field in terms of
problems addressed; evolutionary trends in information
retrieval as a major branch of information science; the
relation of information science to other fields, most no-
tably librarianship and computer science; and educa-
tional models and issues. Conclusions explore some
dominant trends affecting the field.
