Last, Catherine Davidson and Martha Kyrillidou discuss the use of MINES for Libraries® by the Ontario Council of University Libraries, a 21-member library consortium. The consortium is using this brief point-of-use survey protocol to collect data on the value and impact of the rich electronic resources provided to students and faculty. Deeper understanding of user behavior in the virtual environment is a key element in articulating the value of networked electronic services and MINES for Libraries® is a proven useful method. Furthermore, the influence and importance of this protocol in future years is likely to increase. This RLI issue on assessing library performance is timely for readers who will be participating in two upcoming events: the ARL-CNI Forum on Achieving Strategic Change in Research Libraries (October 14–15, Washington DC) and the Library Assessment Conference (October 25–27, Baltimore MD). Proceedings from both conferences will be made available on the ARL website after the events, enriching our understanding of these issues in multiple new ways. We invite the community to actively engage in the debate about the strategic aspects of library value and capturing the evidence, because few truths are self-evident.
