This chapter explores the cut-up as an active, affirmative and performative technique; a critical intervention in the production of language and human subjectivity. It examines historical uses of cut-up methods, from the collages and cut-up works of the Dadaists and the Beat writers, back to the early modern practice of commonplacing books. It highlights the importance of technology–from the xerox machine to keyboard shortcuts—in opening up the reworking of words, sounds and visuals to a wider population. Finally, it explores how remix theory has been instrumental in engaging issues of authorship, originality, and ownership that cut-up practices pose.
