ProQuest has published the key findings of a 2018 survey and white paper, 'Why DDA is here to stay'. The study received input from 449 librarians around the world with more than 99% of respondents working at academic libraries.
A summary of key findings:
- 92% of respondents said that DDA (demand driven acquisition) was the acquisition model that their library used the most often for e-books when evaluating DDA alongside other acquisition models
- 93% percent of respondents said that their library used multiple acquisition models to obtain e-books, with 35% reporting that they use four or more models
- the above shows an increase from ProQuest’s 2016 Global Purchasing Trends survey, where 70% of libraries reported relying on multiple acquisition models and 15% relying on four or more models
- less than 30% of libraries reported they are not using DDA for e-books, reasons for this are cited in the whitepaper
- usage-driven tools are helping libraries to offer the broadest and most relevant selection of titles to users
The whitepaper also looks at how DDA is changing as it continues to gain traction in libraries. This includes how many tools and services have been added to provide librarians with more control over their DDA programmes – including price limits, limits per patron, and librarian mediation.
