    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
    Presents an informetric investigation of an information retrieval vocabulary which is built into a model to quantify mathematically relations within and between terms thorugh optimal relations, uncertainty or noise, and non-identification (silence)
