This original study explores Milton's relationship to the seventeenth-century book trade. Critics have often assumed that Milton presided over all stages of his texts' creation, and little has been said about his dependence on other people for producing his works. Examining Milton's changing historical circumstances with special attention to his texts' material production, Stephen B. Dobranski shows in a series of provocative and original case studies that Milton benefited from a collaborative process of writing and publishing, working with amanuenses, acquaintances, printers and publishers in dramatic and surprising ways.
