I received a research grant from the Hagley Library in 2019 to visit their collections (and incredible location!). You can read about some of the materials I found in the collections in a March 2021 post I wrote for their research blog here. They include a Jacquard-woven image of Independence Hall and some anecdotal evidence that punch cards have played a gendered role for centuries.
In addition, last year Gregory Hargreaves interviewed me about my dissertation project, which can be accessed either by video or podcast. I am embedding these below as well.
