Title

Classing and indexing : a comparative time study

Source

International classification. 19(1992) no.4, S.205-209

Year

1992

Abstract

A total of 16 classifiers made a subject analysis of a set of books such that some of the books were first classified by the UDC anf then indexed with terms from the General Finnish Subject Headings while another set were processed in the opposite order. Finally books on the same subject were either classifies or indexed. The total number of books processed was 581. A comparison was made of the time required for processing in different situations and of the number of classes or subject headings used. The time figures were compared with corresponding data from the British Library (1972) and the Library of Congress (1990 and 1991). The author finds that the contents analysis requires one third, classification one third and indexing obe third of the time, if the document is both classified and indexed. There was a plausible correlation (o.51) between the length of experience in classification and the decrease in the time required for classing. The average number of UDC numbers was 4,3 and the average number of terms from the list of subject headings was 4,0
