Abstract:

There are no successful cases on approval plans or PDA in China, and only a few academic librarians pay attention to approval plans while many do research on PDA. This article tried to clarify the logic relationship between these two bookselecting models in theory and to find integrating cases to explore the possibilities of the integration in order to offer a new option for book selection. It analyzed the pros and cons of both models and the coverage differences of printed and digital books to conclude the probabilities and feasible measures of the integration. It also did research on integrated cases in Kansas University Library, library of California State University at Fullerton and Penrose Library of University of Denver to prove the advantages of the integration. Although approval plans and PDA are different bookselecting methods and concepts, they do not take place of but make up for each other’s deficiencies to optimize the effect of collection development. Based on these, it suggested that library science researchers and academic librarians in China digest and absorb advanced ideas and practice completely, and publishers, library vendors and academic libraries in China take their own responsibilities to realize a hybrid collection development model integrating approval plan and PDA.
