UO History Professor Daniel Rosenberg Rosenberg is interested in time: how we perceive it, and the various means we use and have used to depict it. He also loves games, charts, graphs and ephemera from long-gone days. To share these passions with a wider audience, he teamed up with UO Libraries and created the digital archive TimeOnLine.

With the support of a prestigious Digital Humanities Start-Up Grant from the National Endowment for the Humanities, the team developed digital tools that allow users to interact with centuries-old devices for representing, tracking, and keeping time.
