Communications—A Comment on Managing Library Collections
评论了Sinha和Clelland（1976）提出的图书馆馆藏管理模型，该模型帮助决定每年应采购多少特定类别的书籍或期刊，以及这些资料应在活跃馆藏中保留多久。
In Sinha and Clelland (Sinha, B.K., R. C. Clelland. 1976. Modeling for the management of library collections. Management Sci. 22 (5, January) 547–557.) a set of models is developed to aid in the management of library collections. In particular, two questions are addressed: 1. How many items in a given class of books or journals should be acquired in a given year? 2. How long should such items be retained in the active collection?
