A collection of twenty-three lexical resources in information science, published in both the United States and Europe between 1960 and 1967, was analyzed with the purpose of tabulating the occurrence of different terms in them. This analysis, accomplished by means of a matrix generated on the IBM System 360 Model 40 computer, quantified the terminology, fulfilling the objectives of determining the content of information science language and the frequency with which its concepts have been recorded. This examination of lexical aids showed that there was no existing formal structure for the discipline of information science and that the resources examined tended to reflect the viewpoints of their authors. A series of tables illustrating the frequency of both generic and specific terms appearing in the sources examined is given. Also included in the document is an annotated inventory of the source materials: thesauri, vocabularies, term lists, and classification schemes. (Author/CM)
