"The City Amplified: Oral Histories and Radical Archives" is a collection of ten commissioned essays that reflects the creative and intellectual energy of the working group of the same name. We met as part of the Andrew W. Mellon Seminar on Public Engagement and Collaborative Research, hosted by The Center for the Humanities at The Graduate Center of the City University of New York. My gratitude goes to all members of the working group, including those not included in print here: Kemi Ilesanmi, Diane Yoong, Jaime Shearn Coan, Allison Guess, Lauren Capellan, DeeArah Wright, Elena Martínez, Joshua Brown, Denisse Andrade, Polly Thistlethwaite, Michelle O’Brien, Ugeita Tewari, Linta Varghese. And I’m forever thankful to Samip, Walis, Sady, Yvette, Hatuey, Gabrielle, Shawn(ta), Becky, Maggie, and Molly for contributing to this collection. Finally, all of this was made possible by the brilliant Center for Humanities staff — Kendra Sullivan, director of the Mellon Seminar, Alisa Besher, Jordan Lord, and Sampson Starkweather. And I’m indebted to Allison Guess, editor extraordinaire. In short, thank you.
