文章以美国法布罗大学图书馆开展的实践为例,深入剖析了其基于PDA(Patron Driven Acqu-isition)的三个代表性的合作项目,并得出四点启示:在共建共享模式下考虑存取和拥有的馆藏模式;以读者需求为导向,同时适当加以规范;利用电子商务和快递服务,让读者先睹为快;利用现有图书馆合作团体,开展试点项目。 Taking the practice carried out by the University of the American Library of Buffalo as an example, the article deeply analyzes its three representative cooperation projects based on PDA (Patron Driven Acquidentization) and draws four enlightenments: In the co-construction and sharing mode Consider access and possession of the collection model; Readers demand-driven, while properly standardized; Use of e-commerce and courier services, allowing readers to preview; Use of existing library cooperative groups to carry out pilot projects.
