2=1,2; 1+1=1, 2; etc.

Hamburg: Self-published, 1976. One of 200 copies (Bippus 18); remarkably clean, in plain white wrappers with hand-stamped titles to front and rear covers. Very minor spotting to cloth-tape spine, with bumping to margin of rear cover; overall near fine. Scarce, with only 2 OCLC records located in North America (Princeton, Clark).. Thick quarto. With her artist's book 1975, Hanne Darboven began her lifelong project of "writing time"—a sort of existential filibuster where she transcribed lines from the likes of Baudelaire, Heine, and Sartre using a variety of abstract operations, both logical and absurd. Writing as a form of drawing. One year later—under the post-mathematical title 2=1,2; 1+1=1,2; etc.—Darboven expanded upon that previous work by appropriating a series of additional texts from Sartre and Simone de Beauvoir, quite literally accounting for the passage of time through the addition of volume (240 facsimile manuscript leaves versus 80).
