When poetry was printed, poets and their publishers could no longer take for granted that readers would have the necessary knowledge and skill to read it well. By making poems available to anyone who either had the means to a buy a book or knew someone who did, print publication radically expanded the early modern reading public. These new readers, publishers feared, might not buy or like the books. Worse, their misreadings could put the authors, the publishers, orthe readers themselves at risk. 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 itselfshaped-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.
