Books, like hands, hold our attention. As early as the 12^th century, writers began drawing hands in the margins of their books to point to important passages. Such a device gradually passed into typescript and became a commonplace of printed books. It looked like this: ☞. The pointing hand in the book stood for the way books themselves were like pointers, making the world graspable. If books open us out into the world, they also constrain. They bring the world down to size, inoculations against the problem of patternlessness.

In the 19^th century, readers witnessed the birth of reading as touch, in the form of Louis Braille’s invention of a dot-matrix reading system for the blind in 1824. The method derived from an earlier request by Napoleon for a code that could be read by his soldiers at night in the field without the use of light. Braille’s innovation was to make the dot-matrix representation of letters small enough to correspond to a single touch of the finger. It made reading digital in a very literal sense. By the end of the century, libraries such as the National Library for the Blind in Britain contained over 8,000 volumes in braille, one of many subsequent technologies that aimed to bring reading to the visually impaired.

The turn of the 20^th century was a period of numerous experiments with the tactility of reading, both practical and impractical, culminating in the modernist revival of experimental books between the world wars. Books made of sandpaper, cardboard, cheap notebook paper, wood, and even metal were some of the many ways that artists experimented with the touch of reading. In the Russian artist El Lissitzky’s celebrated Architecture of VKhUTEMAS (1927), we see how the disembodied hand of the divine voice from the medieval book has returned, now in the form of the drafting hand of modern science. With the compass needle seemingly woven into the hand’s grip, we can see Lissitzky performing a subtle visual pun. The compass needle is imagined to stand in for the sewing needle, one of the original tools of bookmaking through the sewn binding of the book’s spine. For the Russian avant-garde, the rectilinearity of modernism—the cube, plane, column, grid—was as much born from the book as it was the industrial Gargantua of the new machine age. The handbook was one of modernism’s secret muses.
