This essay presents a bibliometric survey of dedications and addresses to the reader in plays printed between 1559 and 1642, and compares their rates of occurrence in plays from the professional theatres with those from nonprofessional contexts. Contrary to the critical commonplace that the establishment of early modern literary culture saw the decline of patronage and the rise of the figure of the reader, the rates of publication of dedications and addresses to readers suggest the opposite. The essay documents a striking absence of attention to readers in the preliminaries of playbooks and finds that the dedication was the more popular form of prefatory address for both professional and nonprofessional plays.
