The multitude of voices arising from these tiny books is astounding: they seem to have circulated fluidly among owners, from individuals to institutions, from one city to another, from the status of mandatory school readings to that of precious collectibles. A vortex of numbers (dates of reading and offering, prices), of titles and names catches the eye before it can reach the text. In order to experience the vortex more vividly, the collage does better work than the simple inventory. As for the content, more to come.
