The document describes a case study of an impact measurement tool called "Storing Stories" that was created at a hackathon to gather user experience feedback and measure the impact of library services. It discusses how the tool was developed and piloted at Stirling libraries to collect anecdotal stories from users linked to strategic priorities like reading, digital inclusion, economic wellbeing, and more. The tool helped demonstrate the tool's impact by mapping user stories to indicators. There are plans for further development and expanding the pilot nationally.
