As electronic books and electronic journals have become more prevalent, so too do the number of electronic resources outages related to those resources. This paper, distilled from a presentation delivered at the 2015 American Library Association Midwinter Meeting, describes the implementation of a new tracking system for electronic resources outages at the University of Michigan (UM). It elaborates on the decisions that went into building the system and the insights gleaned from analyzing a year's worth of outages. It is hoped that such data might better inform decisions related to electronic resources at UM, and that its collection might inspire similar data- driving tracking elsewhere.
