This book asks new questions about how Shakespeare engages with source material, and what should be counted as sources. The essays demonstrate that source study remains an indispensable mode of inquiry for understanding Shakespeare, his authorship and audiences, and early modern gender, racial, and class relations, as well as for considering how new technologies redefine our understanding of Shakespeare. They revise conceptions of sources and intertextuality to include terms like "haunting," "sustainability," "microscopic sources," "contamination," "fragmentary circulation" and "cultural conservation, examining print and material culture, theatrical paradigms, and oral narratives.
