What is Demand-Driven Acquisition in EBSCOhost Collection Manager?

Demand Driven Acquisition or DDA is a method for acquiring eBooks that allows patron usage to contribute to the eBook selection process. Using a DDA collection, your institution can make a select set of eBooks available for patrons to browse on EBSCOhost, but your institution would only be charged for eBooks that experience substantial usage.

Substantial usage is defined by publishers as:

  1. Browsing the eBook for up to 10 minutes
  2. Turning up to 10 pages in the eBook
  3. Downloading any portion of the eBook
  4. Emailing any portion of the eBook
  5. Printing any portion of the eBook
