This guide for setting up a job development/job placement file is based on information obtained from the following sources: (1) site inspections of filing systems used by several Illinois and Missouri high schools and community colleges; (2) a questionnaire mailed to fifty-three job placement specialists, of which 41.5% were completed and…

SOME MACHINE-PRODUCED INDEXES ARE COMPARED TO ASSIST IN DECIDING ON THE FORMAT FOR A PROPOSED INDEX. THE OBJECTIVES OF AN INDEX AND THE SEARCH PROCEDURE ARE ANALYZED, AND AN EXPLANATION AND A RELATIONSHIP IS GIVEN FOR KEY-WORDS-IN-TITLE AND KEY-REFERENCES OF THE SAME ARTICLE. BASED ON THE COMPARISON OF THE INDEXES, A 53- YEAR CUMULATIVE INDEX WAS…

A set of twenty five questions was processed against a computer-stored file of 9159 document references in the field of ferrous metallurgy, representing the 1965 coverage of the Iron and Steel Institute (London) information service. A basis for evaluation of system performance characteristics and analysis of system failures was provided by using…

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…
