Time-series data can be used to understand trends and changes over time. In addition to data collected automatically by library systems and services, University Library has been utilizing timestamped data collected by other technology services such as the Wi-Fi and EZproxy data to assess the usage of library spaces and online resources. This presentation is a reflection of the University Library's journey down a not-so-haunted trail of data and "time," which led to treats in forms of engaged conversations, collaborations, and opportunities.
