The cut-up technique is an aleatory literary technique in which a text is cut up and rearranged to create a new text.
The concept can be traced to at least the Dadaists of the 1920s, but was popularized in the late 1950s and early 1960s by writer William S. Burroughs, and has since been used in a wide variety of contexts.
The cut-up and the closely associated fold-in are the two main techniques:
Cut-up is performed by taking a finished and fully linear text and cutting it in pieces with a few or single words on each piece. The resulting pieces are then rearranged into a new text.
Fold-in is the technique of taking two sheets of linear text (with the same linespacing), folding each sheet in half vertically and combining with the other, then reading across the resulting page.
