This document discusses demand-driven acquisition (DDA) at the University of Denver (DU). It summarizes DU's experience with DDA programs like netLibrary and EBL. Some key points: - DDA allows DU to provide a much broader collection by matching acquisitions to immediate demand through short-term loans and purchase-on-demand. - Through EBL, DU was able to provide access to over 10,000 ebook titles while spending less per transaction than anticipated list prices. - DU aims to expand its multi-format DDA model to include more vendors and formats like print-on-demand. - Long-term, DU hopes to maintain a permanent collection through DDA while

the Consideration Pool

23. Filling the Pool
 Approval process
 Broader criteria
 Inclusion rather than exclusion

24. Adding/Removing Records

 Rules for permanent removal

27. Use Shapes the Pool
 Titles that are used remain available
a bit longer
 Removing titles = unhappy users

28. A Permanent Collection
 Some titles are core
 Establish criteria for
permanent/longer-term availability
 Title-by-title
Series
