In an artistic sense, as Lorraine York notes, "Critics and readers feel a persistent need to 'de-collaborate' these works, to parse the collective text into the separate contributions of two or more authors". This is part of a tradition in criticism to view collaboration as a subset or aberrant kind of individual authorship – such that later readers could separate out by examining the collaborative text. Particular examples of this approach to criticism include Cyrus Hoy who studies authorship in the Beaumont/Fletcher plays.
