Abstract
In order to seek a new method of book evaluation and realize book resources sharing among the regional university libraries, we think that library should collect books of the high utility value in the case of limited funds. We proposed a changing Bellman equation as a utility function and used the explicit functions of the book usage factor and the book usage half-life derived from the utility function as an evaluating method of the collecting books. The results from empirical data given some conclusions such as the varieties diversity, the collected risk, the tendencies of reading varieties, species continuity and so on and a librarian can use the utility management to supplement the collections management.Electronic supplementary materialThe online version of this article (doi:10.1186/2193-1801-2-61) contains supplementary material, which is available to authorized users.
Highlights
The relationship between supply and demand is undefined in current books from existing editing and publishing
The basic concepts of the utility management based on various expositions above all can be extracted from the utility (Say 1982) and the utility value (Zheng 2003) (Yu and Hu 2007) and the utility function (Zhang and Chen 2000) (Koksalan and Ozpeynirc 2009) and the utility theory (Farquhar 1984) (Dong 2007) as a management theory
Bellman equation in utility functions has the property of the multi-stage decision-making under uncertainty modeling and very adapts evaluating to collecting books and using books as a method in library management
Summary
The relationship between supply and demand is undefined in current books from existing editing and publishing. The financing and product prices are becoming competing target among the resources consortia, which result in the cycle and flooding of the phenomena in home market, such as a single kind, vulgar content, lack of language and poor performance etc. Are these not able to meet the needs of the multi-level crowds, multi-regional custom, multi-species innovation, multi-fields academic inquiry as the scale, but these don’t reflect adequately the cultural prosperity and technology in the digital age. Throughout the book supply chain, it is common that publishing group is to pursue profit maximization and authors are to compile the non-standard with the same materials from different publishers.
