Demand-Driven Acquisition: Minor Shift or Fundamental change
•Download as PPTX, PDF•
1 like•536 views
This document discusses demand-driven acquisitions (DDA) models that allow libraries to purchase ebooks based on patron usage rather than upfront selection. It outlines the DDA program at the University of Denver, which loads records for tens of thousands of ebooks and allows short-term loans before purchase. Data shows increasing usage and purchases through the program. The author advocates expanding DDA to include multiple ebook vendors and formats, and making as much content as possible accessible within the library's budget. Publishers are urged to make ebooks available through all DDA models and ensure content is discoverable.
