Learn how three libraries use apps to transform services, operations, and assessment. One library developed a tablet-based app to provide just-in-time reference services and an alternative to cutting services or staff. Another library utilizes iPads on both sides of the circ desk from circulating iPads to patrons to apps for tech services, reference, and circulation. The third library creates its own free suite of apps to collect and analyze data, create reports, and demonstrate the importance of their liaison.
