I wish to thank David Baker, Claire Bourne, Joshua Calhoun, Roger Gaskell, Megan Heffernan, Adam Hooks, Zachary Lesser, Mary Caton Lingold, Tara Lyons, Randall McCloud, Melissa Sanchez, Thomas Ward, and Sarah Wasserman for commenting on or fielding questions about an early draft of this chapter, as well as audiences at the “Media Old and New” working group at University of Delaware, the Material Texts Seminar at University of Pennsylvania, the Songscapes conference at University of Toronto, and the Renaissance Society of America conference (2016 and 2018) for their insights and helpful discussion. Thank you also to my collaborators Zoe Braccia and Liza Daly, without whom Manicule and the Humphrey Moseley social network would not exist. The following curators and librarians offered invaluable assistance: Wayne Hammond, H. C. Harron, Kathryn McKee, Jo Maddocks, Sandy Paul, Suzanne Karr Schmidt, Jane Siegel, Catherine Sutherland, Stephen Tabor, and Emily Walhout. I extend my sincere appreciation to each of them. I reserve especial thanks for Christian Algar at the British Library and Aaron Pratt at the Harry Ransom Center, who consistently go above and beyond in assisting me and other researchers, and Terence Smyre at the University of Minnesota Press for his incredible work staging this chapter. The digital resources for this chapter were produced with the support of the Price Lab for Digital Humanities, the Center for Undergraduate Research Mentoring at the University of Pennsylvania, and an NEH-Mellon Fellowship for Digital Publication. This chapter is, of course, still a work in progress, and any errors remain my own.
