Collection development librarians have long struggled to meet user demands for new titles. Too often, required resources are not purchased, whereas some purchased resources do not circulate. E-books selected through patron-driven plans are a solution but present new challenges for both selectors and catalogers. Radical changes to traditional technical services workflows are required, and selectors must modify the selection process to give more choice to the user. Rutgers University librarians have adopted an innovative new technical services workflow and collection-development model to manage a successful, patron-driven acquisitions project for e-books in the fields of math and computer science.
