Doubtful Readers: Print, Poetry, and the Reading Public in Early Modern England focuses on early modern publishers’ efforts to identify and accommodate new readers of verse that had previously been restricted to particular social networks in manuscript. Focusing on the period between the maturing of the market for printed English literature in the 1590s and the emergence of the professional poet following the Restoration, this study shows that poetry was shaped by—and itself shaped—strong print publication traditions. By reading printed editions of poems by William Shakespeare, Aemilia Lanyer, John Donne, and others, this book shows how publishers negotiated genre, gender, social access, reputation, literary knowledge, and the value of English literature itself. It uses literary, historical, bibliographical, and quantitative evidence to show how publishers’ strategies changed over time. Ultimately, Doubtful Readers argues that although—or perhaps because—publishers’ interpretive and editorial efforts are often elided in studies of early modern poetry, their interventions have had an enduring impact on our canons, texts, and literary histories.
