Book excerpt: This Element Paratext printed with new English plays has a lot to tell us about what playwrights were attempting to do and how audiences responded, thereby contributing substantially to our understanding of larger patterns of generic evolution across two centuries. The presence (or absence) of twelve elements needs to be systematically surveyed. (1) Attribution of authorship; (2) generic designation; (3) performance auspices; (4) government license authorizing publication; (5) dedication; (6) prefaces of various sorts; (7a-b-c) list of characters (three types); (8) actors' names (sometimes with descriptive characterizations-very helpful for deducing intended authorial interpretation); (9) location of action; (10) prologue and epilogue for first production. Surveying these results, we can see that much of the generic evolution traceable in the later seventeenth century gets undone during the eighteenth-a reversal largely attributable to the Licensing Act of 1737.
