New Whitepaper:  Why DDA is Here to Stay

Demand-driven acquisition, or DDA, a usage-based acquisition model for books, has been available for more than a decade. We conducted an extensive survey to get a snapshot of where DDA stands today with libraries around the world. Read the new ProQuest whitepaper and hear directly from librarians who use it.

  • • The basics of DDA and other types of usage-based acquisition
  • • Why some libraries don’t use DDA
