‘Oei’ is the title of a notebook that Guy Rombouts (b. 1949) filled from front to back with the word ‘oei’, during a week in the month of July in the year 1976. (‘oei’ [uj] is a Dutch-language interjection uttered to express a spontaneous reaction to an unexpected occurrence. [The closest English equivalent would be ‘ouch’.]) Weaving this word as one long stream of thought through the pages of the book under ever-changing guises creates a primal litany in which mistakes are sung over and over again in all their impossibility. The facsimile of the notebook ‘oei’ is published in full and full size as Posture Pockets N° 3.
