User experience (UX) internships generate ideas for usability projects, improve the design of existing and new services, investigate users' motivations and behavior, and build transferable skills for interns. This case study proposes a micro-internship model, grounded in the design cycle, that institutions can adapt to address their libraries and students' needs. The model employs a three-stage process--discover, understand, and create--and it also provides best practices on structure, engagement, resource selection, and skill acquisition with usability methods. The article includes three case studies of UX undergraduate intern projects completed in two weeks or less using a mini-portfolio format.
