Research data services--support offerings which enable and improve data-intensive research--have garnered sustained attention from library research support service providers for nearly two decades. Libraries have played a leading role in developing research data services, and on most university campuses they provide the largest and most diverse services. While there is general consensus that institutions should provide a coordinated research data services support infrastructure to their researchers, determining the most effective way to do this has proven more difficult, especially in light of the fast-paced technological changes that have precipitated new forms of research collaborations, methodologies, and discoveries. In the interest of providing up-to-date data to inform university decision making, Ithaka S+R has collaborated for the past two years with 29 US and Canadian institutions to develop strategies for improving the coordination of research data support services offered across different campus offices. The project included the collection of institution-level data about the range and location of current data services across campus, design workshops geared toward creating new or strengthening existing data service infrastructure, and cohort-wide and individualized meetings to discuss topics and strategies for delivering effective research data services. In March 2024, Ithaka S+R published findings from a landscape survey of data services offered at colleges and universities in Canada and the US. Now, this report shares additional findings from interviews with researchers exploring their practices and experiences using research data services, conducted by the university partners. The interviews provided a wealth of information about the data management needs and challenges of researchers as well as their current level of engagement with campus data services.
