How much are technical services worth? Using the contingent valuation method to estimate the added value of collection management and access

This paper reports on an application of the contingent valuation method in order to establish a dollar estimate of the value added to a collection by a library's technical services. The overall benefit-cost ratio of the Wagga Wagga City Library, in New South Wales, Australia, was estimated to be 1.33:1, whereas the benefit-cost ratio of its technical services was found to be much higher, at 2.4:1, indicating the particular importance of this work. The use of stated preference techniques such as contingent valuation is discussed, with reference to library and technical service contexts.
