In this article, the author discusses the benefits offered by integrated library systems (ILS) for making more informed decisions. Library software vendors, realizing ILS products can reveal business intelligence, have begun to offer tools like Director's Station to help library managers get more out of their data, and librarians are taking advantage of the benefits. Experts like Mark Dahl, Elizabeth Thomsen, and Richard Jackson can increase that same awareness, closing the gap between the questions library leaders have and the answers the ILS can provide. When more librarians can dig into ILS data with their own hands, data planning will supplant data mining in librarians' priorities for making smarter, evidence-based decisions.
