During several years Jeroen Peeters collected notes left behind by readers in library books: faded reader tickets, scraps with notes, a shopping list, train tickets and other little papers used as bookmarks. He noted each time the date and the book in which they were found. Afterwards he wrote commentaries to this collection, an essay on alternative reading practices, marginalia and extra-illustration, on the exchange between readers and the imaginary community lingering in all those library books.
