“Most libraries around the world use the Dewey Decimal Classification System (DDCS) to list and categorize books. It was an attempt to organize all knowledge into ten main classes, which are further subdivided into 100 divisions and 1000 sections. This makes the DDCS appear purely numerical and infinitely rational. However, DDCS is regularly revised, reflecting how culture, ideology, and the perception of knowledge change over time. As a result of these changes and to provide for future alterations, 89 of the 1000 sections in the system are classified as ‘unassigned.’ For this issue of Shifter, we invited artists, writers, activists and scholors to comment on, disturb, and restructure the logic of this system by adding new categories to fill the unassigned spaces. These comments, reflections, parasite systems or prosthetic extensions all expand on what is structurally ‘knowable’ within the institution of the public library, by opening up the possibilities held within its undefined categories.”
