Peter H Barnett: Time Trap (Assembling Press, 1980) is composed of twelve 8 1/2" by 12" sheets folded and stapled in booklet form. A loop of thread connects the midpoint of each page. The work explores various dimensions of the book form through four series of diagrams accompanied by texts and instructions. These graphic-textual progressions migrate over the outer margin of adjacent pages, through the gutter on the inside of a folded sheet, through the gutter on the outside of a folded sheet, or across the gutter from one page to the next. Three of the graphic progressions are v-forms which narrow and elongate as they migrate. The fourth is a string of numbers 1-12. The texts associated with each progression express attitudes of waiting, disorientation and entrapment. The four progressions are all there at once, but never meet: only one progression can be pursued by the interactive reader at a time, hence the title. The accompanying introduction, "Open Structure for a Philosophical Experiment" originally appeared in An Eighth (Critical) Assembling -- Source of annotation: Marvin or Ruth Sackner.
