This document discusses mobile UX for libraries. It emphasizes the importance of understanding users through research, knowing the mobile context, and creating simple interactions. Specifically, it recommends forming a student design group to implicitly understand user needs. It also identifies key mobile contexts like limited screens and attention. Finally, it proposes solving four problems for academic library mobile users: vendor fragmentation, catalog search, data portability, and authentication. The overall message is that mobile UX requires a user-centered culture, iterative design based on context, and focusing on simple interactions to solve user problems.
