Title

Obsolescence and stress : a study of the use of books on open shelves at a university library

Abstract

Reports the results of a study at the main library of Cape Town University, to investigate complaints about ageing book stock and declining resources and observations that many books were hardly circulating. The study aimed to establish the proportion of the books in the library which were actively circulating and whether the accepted phenomenon of decline in use with age, or obsolescence, would be supported in an environment where a reduction in the purchase of new books was evident. Two separate investigations were conducted: a diachronous study of accession dates, classification numbers and date labels of the open shelf collection; and a synchronous study of books on loan during the period of investigation. The resulting database consisted of 2654 and 1023 records respectively. Evidence suggests that older books, do not exhibit the expected characteristics of obsolescence and, while a certain measure of decline of use with age was demonstrated, such decline may be reversed in times of decreasing resources or increasing demands from existing resources. Suggests that the library could develop an informed weeding policy that will enable it to remove from the shelves those materials that have remained unused or little used for 25 years or more
