    Abstract
    Reports results of an automated search of the term 'information technology' and 20 related terms in the ERIC database, 1982-1991, which revealed data related to: scientific production relating to information technology; core journals; types of documents; types of authors and their output; sponsoring institutions; publishing output by country; desciptors; and related terms. The following bibliometric laws are applied: Bradford's law; Lotka's law; and Spearman's and Pearson's laws. Provides an insight into the role of bibliometrics as a scientific discipline for the study of the development of new technologies and their impact on information activity
