Pi(e) Day 2024: Recap!

If you'd like to see what we made this year, many participants in our Pi(e) Day virtual event contributed to a Padlet with pictures, recipes, and stories!

Keeping Up with the News

Pi(e) Day 2024 has come and gone, but that just means we're a few months closer to Pi(e) Day 2025! 

We cross-posting information to the Food Collections listserv and we keep a running list of contacts for Pi(e) Day events. Please reach out to one of our organizers (Juli McLoone, University of Michigan Special Collections Research Center; Maggie Vanderford, University of Michigan, Clements Library; Kira Dietz, Virginia Tech Special Collections & University Archives; Emily Wahl, Folger Shakespeare Library), if you'd like to be included and get a head's up for next year!

In the meantime, we'll be adding some new content to our LibGuide and you're welcome to check out what we've been collecting from past events (hover over the arrow by "Past Pi(e) Day Info" to bring up a list of previous years. 


Pi(e) Day and the Great Library Pie Bake-off events happen on or around 3/14 of each year. Depending on the organizers' planning, which starts in the fall, we try to announce our theme and plans in January for March. This LibGuide is our living resource that includes links to materials produced in past events, some of our collected recipes, our shared history, and even content that talk about Pi(e) Day. If you have suggestions for or questions about the LibGuide, contact Kira Dietz (! If you have questions about Pi(e) Day, contact Kira and she'll connect you with the other organizers!
