    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

    Abstract
    Bradford's law is widely used in collection development to identify the most productive periodicals, but does nott take into account the variables of frequency of publication and number of years of publication during a particular time span. Hence not all periodicals necessarily have the same opportunity to publish relevant articles. To test this hypothesis, the productivity of American sociology periodicals during 1987-91 was analysed and shown to correlate with frequency of publication and number of years of publication, giving a more accurate representation than using Bradford's law as originally formulated
