OCLC now supports Demand-Driven Acquisition (DDA) with WorldCat knowledge base


OCLC has published a new document that outlines options for implementing Demand Driven Acquisitions (DDA) programs using the WorldCat knowledge base. DDA allows libraries to make e-books discoverable to their users prior to purchasing. A title is triggered for purchase via ‘significant use’ by users. The individual library can define what constitutes the levels of ‘significant use’ necessary to trigger the purchase direct with the supplier.

Ebook Library (EBL) is the first provider supplying data to this service, with ebrary and others to follow soon. EBL's automated data feed automatically updates the OCLC knowledge base, streamlining workflows around DDA.

“Today, people want instant access to e-resources, but for many libraries, pressure on budgets makes purchasing collections speculatively, increasingly unsustainable,” said David Whitehair, Senior Product Manager, Metadata Management, OCLC. “DDA takes the guesswork out of traditional collection building and ensures budgets go towards what is actually being used. The integration of regular feeds of high-quality metadata to libraries’ discovery services is critical to this process. After all, the success of any DDA program rests in the user’s ability to find and identify the titles they want prior to the library’s purchase of them. Using the WorldCat knowledge base to provide ongoing automated feeds from publishers like EBL brings huge workflow efficiencies for libraries and seamless discovery-to-access for users.”

The National library of the Netherlands is already using the service and Jan Bos, Head of Collections at the library explains what it means to them: “Because EBL provides a data feed to the WorldCat knowledge base, our WorldCat holdings are maintained and the titles surfaced in our WorldCat Local discovery interface automatically. This brings efficiencies, but more importantly it means we can offer a much wider collection to our users, who get real-time access to the content that is relevant and useful to them. This ensures we better serve our users, while making the most of our collections budget.”

For more information on how OCLC can work with your library to initiate feeds of collection data to the WorldCat knowledge base, set up holdings on your DDA titles in WorldCat, receive records in your local discovery interface, expose titles in WorldCat Local, manage ILL deflection options as desired, and track purchases in WorldShare Acquisitions please read our online DDA information sheet.
