Our study interviewed librarians in charge of collection development for electronic resources from 15 university libraries in Taiwan. We found that when considering joining a consortium, librarians primarily consulted the subject coverage of a consortium's purchasing list as well as whether more titles would be obtained. The primary advantages of joining consortia are saving money and time in the acquisition of resources and expanding available titles. Most librarians reported no loss of control over their own collection development policies. In general, the librarians were not satisfied with the consortia's leadership and coordination, suggesting that consortia staff should improve their bargaining and negotiation skills.
