This document summarizes several initiatives by the Association of Research Libraries (ARL) related to assessing library services. It discusses LibQUAL+, a survey tool used to measure user perceptions of service quality, and how it has been implemented in the UK through SCONUL. It also introduces TechQUAL and ClimateQUAL as additional assessment tools for IT services and organizational culture, respectively, and provides examples of results from trials of these tools in UK universities.
