读者决策的图书馆采购(PDA)近些年开始迅速地在美国研究型图书馆中得到应用,尤其是以电子图书采购的实践为先导。图书馆以读者需求为导向的藏书补充研究已经历一段时间发展,从传递格式、供应商、读者群、界面等方面都已形成一定的工作流程,也存在一些问题,为今后发展PDA提供了一些启示。 Readers’ decision-making on library procurement (PDA) has been rapidly applied in research libraries in the United States in recent years, especially in the practice of e-book procurement. The research on the supplement of the library, which is oriented by the readers’ needs, has been going on for a period of time. Some work processes have been formed from the aspects of delivery formats, suppliers, readers and interfaces, etc. There are also some problems for the future development of PDA Inspiration.
