Experts or Dummies? Quality of E-Book Pool and User Selections in a Consortial Demand Driven Acquisition Program

Matthew J. Jabaily, Rhonda Glazier


Academic libraries are increasingly purchasing electronic books (e-books) via demand driven acquisitions (DDA) programs.  However, there is no guarantee about the quality of DDA titles. This is especially true for consortially managed DDA pools or when pools include all titles from selected publishers. This study analyzes data from EBSCO’s GOBI acquisitions platform to assess the quality of the pool and purchased titles from the Colorado Alliance of Research Libraries (CARL) publisher-based DDA program. Results showed that most available and selected titles were appropriate for academic libraries. Popular and lower level academic titles made up a relatively small portion of the DDA pool but were selected at a proportionally higher rate than other titles. The DDA pool was weighted towards titles that had been previously purchased by few GOBI libraries, but users tended to select titles that had been purchased by more GOBI libraries. Implications of these results are discussed from the point of view of a consortium member library using the DDA program as a supplement to its broader collections of print and electronic books.
