Many institutions produce research data with legal protections, whether through the Health Insurance Portability and Accountability Act (HIPAA), Family Educational Rights and Privacy Act (FERPA), the Common Rule, or intellectual property protections associated with trade secrets. There are well-established mechanisms for sharing data in a controlled way, such as Data Use Agreements and via systems like health information exchanges yet few institutions use existing platforms to enhance visibility and access to research datasets. We see a valuable opportunity for librarians to improve the visibility of protected data, improve documentation and support for the researchers who use these mechanisms, and develop strong relationships with administrative units in this area. This presentation (briefly) describes initial work to pilot a data catalog at Indiana University Purdue University Indianapolis (IUPUI) to enhance the discovery and sharing of protected data generated on campus for reuse in appropriate and controlled ways. This work involves the development of a use case template, modifications required for the existing data repository, and the workflow for review and approval of the requested use. This pilot project has relied heavily on partnerships with our institutions' School of Medicine and School of Public Health as well as the University HIPAA Privacy Officer and HIPAA Security Officer.
