This document summarizes presentations from the 2010 Charleston Conference on patron-driven acquisition (PDA) of ebooks. It discusses: 1) Results from the University of Denver's PDA program with EBL, which saw over 1,400 short-term loans of ebooks, saving the university over $226,000 compared to purchasing all browsed titles. 2) A survey of university presses that found over half were unfamiliar with their library's PDA activities and most believed PDA could negatively impact monograph sales and their ability to forecast sales. 3) Challenges in budgeting, maintaining collections, and rethinking interlibrary loan models under PDA discussed by presenters.
