At the request of Sno-Isle Libraries, WA, OverDrive has developed a demand-driven acquisition (DDA) model for popular ebooks, enabling patrons to discover thousands of titles for which the library has not yet purchased a license. When a user checks out one of these titles, Sno-Isle is invoiced, and the ebook is added to the library’s collection in a transaction that appears seamless to the patron.
OCLC has begun supporting demand-driven acquisition (DDA) through the WorldCat Knowledge Base. DDA pioneer and ProQuest subsidiary EBL will be the first ebook service to provide data, with sister company ebrary to follow soon. Interest in DDA is well established, but there are still challenges facing adopters of these programs.
Ebook Library (EBL), the library ebook platform launched in 2004 by Australian company Ebooks Corporation, has had worldwide success. More than 600 institutions, encompassing thousands of libraries, around the world now use EBL.
The majority, 81 percent, are academic libraries, with another 15 percent of the client base made up of special, government, and corporate libraries; the remaining four percent are split between public and school libraries. Higher education institutions large and small, including three LJ will look at more closely—the University of Texas (UT) at Austin; Wellesley College, MA, one of the famed “Seven Sisters” schools; and Fairfield University, CT—are among EBL’s many clients.
