Demand Driven Acquisitions

Ebooks / Books Now!

Beginning spring quarter 2013, UCSC Library will offer a new method of acquiring English-language books.  Called Demand-Driven Acquisitions (DDA), it provides students, faculty, and staff with access to more information resources while maximizing the Library’s purchasing dollars.  DDA is one of the ways the library is redirecting its reduced resources to keep up with the changing information needs of our patrons. 

  • Phase I provides immediate access to e-books.
  • Phase II, fall quarter 2013, will introduce on-demand purchasing of print books.


What is Demand-Driven Acquisitions?

  • New records for thousands of scholarly books have been added to Cruzcat (the library catalog); additional titles will be added regularly as books are published.
  • Students, faculty, and staff select the books they feel are most needed for their research and educational pursuits directly from Cruzcat.
  •  When you see a title in Cruzcat that is needed for your work, click to get access.
  • Don’t see what you need in Cruzcat?  Faculty, staff, and students can still submit requests for items they don’t find in the catalog.


How will Phase I work?

  • E-book titles are added to Cruzcat as they become available.
  • E-books will be accessible immediately from the link in the Cruzcat record.


How will Phase II work? 

  • Print book titles are added to Cruzcat as they become available.
  • When you see a title in Cruzcat that is needed for your work, click the link to place an order for the print book.
  • Print books ordered will be available for pick-up, on average, between 7 and 10 days after ordering. The speed with which they arrive may vary and depends on how quickly our book vendor can ship the title to UCSC.
  • Users will have the option to place holds on print titles and to be notified when the title is ready for pick up.


What will remain the same?

  • There will be no change to the way non-book (DVD, CDs, video games, scores) materials and non-English language materials are acquired.
  • Students, faculty and staff may still submit purchase requests for specific materials not available in Cruzcat, including items for Reserve.
  • Interlibrary Loan will still be available to borrow materials from another library.
  • Electronic is still our preferred format for materials.  We will buy print versions only if the electronic version is unavailable.


What are the benefits of DDA?

  • Provides access to a greater number of resources for faculty and students.
  • Most cost-effective way to provide access to the greatest breadth of scholarly resources.
  • Patron-selected items get used more often, research shows.


Are other UC libraries doing this?

Yes. Most UC campuses have some form of Demand-Driven Acquisitions. In addition, many other university libraries, including Duke, NYU, and the University of Minnesota have launched DDA programs. Some library systems, for example, the Orbis Cascade Alliance, even have a system-wide demand-driven acquisitions program in place.
