The two-volume 9/11 911 CALLS IN 911 PT. FONT, printed on large US Letter paper, consists of transcript excerpts from emergency calls to the New York fire department—with its 911 phone number—on September 11, 2001. The text is set in an oversized 911 point, which means that it stretches out over two volumes with a total of nine hundred pages (vol. 1: 464 pages, vol. 2: 460 pages). The individual letters go beyond the edges of the page, rendering the printed book almost unreadable. In the PDF, by contrast, the text maintains its readability because it allows for different viewing modes, and the text can be copied into a word processor.

It is in the nuanced interaction between both formats that the full aesthetic potential and political expressiveness of this work unfold, and the explosive power of the historical event documented becomes obvious: the printed version, with its letter fragments, directs our attention to details and highlights the injuries of individual persons as well as the inconceivability of what is happening. The digital format lets us recognize coherences and an overall picture of what is happening. Thus, these two publication formats are not designed as the usual either-or, in which readers can select the format they prefer, but as both-as-also: PDF and print-on-demand complement and merge to form a conceptual unit that generates surplus and overcomes the antagonistic juxtaposition of analog and digital. This makes these hybrids an epitome of our post-digital age.
