The National Endowment for the Humanities has underwritten my work on this project for a number of years, and I gratefully acknowledge the neh Long-Term Post-Doctoral Fellowship at the Library Company of Philadelphia that inaugurated my research in 2010; the neh-sponsored 38th Voyage of the whaleship Charles W. Morgan that gave me more insight into shipboard life and labor; and the year-long neh Fellowship in 2014–15 that allowed me uninterrupted writing time. My research at the archives and institutions listed above was also supported by research awards and grants from the following : the Bibliographic Society of America’s McCorison Fel-lowship for the History and Bibliography of Printing in Canada and the United States, Andrew W. Mellon Foundation Fellowship at the Hunting-ton Library, William Reese Company Fellowship at the John Carter Brown Library, and a Franklin Research Grant from the American Philosophical Society. Two Residential Scholar Awards from the Penn State Institute for the Arts and Humanities/Humanities Institute, as well as the support of the Penn State English Department, College of the Liberal Arts, and Cen-ter for American Literary Studies, have also been instrumental to my work, and I thank Mark Morrisson, Susan Welch, Michael Bérubé, Lauren Koo-istra, Sue Reighard, John Christman, and Robin Schulze.
