With funding from an Institute of Museum and Library Services demonstration grant, librarians of the Undergraduate Library at the University of Illinois at Urbana-Champaign partnered with students in computer science courses to design and build student-centered mobile apps. The grant work called for demonstration of student collaboration strategies and computing workflows that would enable greater access to collections and awareness of library services, while investigating aspects of location-specific mobile digital services. This case study reports grant strategies and goals, app design choices, and student and librarian outputs at the end of the grant.
