The purpose of this research is to study the operation model of Taiwan Academic E-Books Consortium (TAEBC) and its effect on the collection development of university libraries in Taiwan. Methods of this research include interviews and a questionnaire. The findings show that the cooperative model of a working group is the distinguished characteristic of TAEBC, and that it demonstrates the spirit of cooperation among libraries. It is helpful to improve the quantity and quality of library collection, and it also changes the selection and acquisition procedures as well as the work of collection management in university libraries. However, there is a gap between the direction of TAEBC’s selection policy and the expectations of member libraries. Designing a selection mechanism to meet the needs of members with different attributes and continuing to strengthen the effectiveness of promotion will be the next tasks and challenges of TAEBC.
