Abstract This paper examines the materials acquired during a consortial PDA pilot; which of the books are still being used, by which institutions, whether the size of a participating institution or the subject of a book have impact on the continued use of the books, and if there is a relationship between the schools that triggered a PDA purchase and the schools that have gone on to use a given title. Findings suggest that models involving some library mediation may be more effective in meeting the various needs of participating institutions.

联盟 PDA 系列的长期使用：如果他们选择它，我们会使用它吗？*

摘要 本文研究了在联合 PDA 试点期间获得的材料；哪些书籍仍在使用，由哪些机构使用，参与机构的规模或书籍的主题是否对书籍的继续使用产生影响，以及触发PDA购买的学校之间是否存在关系以及继续使用给定名称的学校。调查结果表明，涉及一些图书馆调解的模式可能更有效地满足参与机构的各种需求。
