Missouri State University Libraries launched a demand-driven-acquisition (DDA) model this week as part of its ongoing efforts to develop the libraries’ information services and resources.

DDA is a type of library collection development in which a library purchases materials based on the demonstrated needs of its users. MSU Libraries is the first academic library in the country to integrate DDA with FOLIO, its open-source library services platform.

“This shift in collection development supports our guiding principles at MSU Libraries,” said Mohammad AlHamad, e-resource strategist. “DDA is digitally focused and data-informed – it puts purchasing power directly in the hands of our users.” 

In a typical DDA exchange, a patron will browse for e-books in a search engine or discovery service. When a title is used in a meaningful way – such as an extended browse, download or print – MSU Libraries will purchase the e-book automatically. The exchange is seamless for both the library and patron. 

“With DDA, University Libraries will now have hundreds of e-book titles loaded to its collection every week from prominent publishers,” explained Rachel Besara, associate dean of libraries. “This model helps ensure our collection stays relevant, accessible, and up to date.”

This usage-driven plan is one of many ways MSU Libraries meets the evolving needs of its users. In addition to DDA, students, faculty and staff can access thousands of e-books through EBSCO resources and databases.
