LeWitt similarly elevated written instructions and conceptual notations to the status of finished artwork, blurring the line between idea and object in ways that directly echo Duchamp's White Box approach to documenting thought processes as art.

Kosuth pursued the same interrogation of authorship, language, and intellectual process as primary artistic material, producing text and document based works that treat philosophical and analytical notation as the artwork itself rather than mere preparation.

Roth produced artist books, facsimile editions, and compiled personal notebooks as multiples that similarly challenged originality and archival authenticity, sharing Duchamp's interest in transforming private intellectual records into reproducible conceptual objects.
