'I Met' (1968-1979/2004) and 'I Read' (1966-1995) by On Kawara
"On Kawara based the entirety of his collection of books, paintings, and drawings on the arbitrariness and subjectivity of the way we measure time. Many of his projects were ongoing, making Kawara himself, as the recorder of time, one of the primary materials in his conceptual works."
