During their 1-week residency, the stonekollektiv (Julia Nitschke and Caroline Anne Kapp) explored performative approaches to the library. This resulted in »instructions for action« that visitors to the library can follow. Through personal memories, individual approaches to the collection are provoked. Chance plays just as important a role as subjective decisions. The telephone number e.g. becomes a personal access code. The Reader shows some magazines that were important for the work of the stonekollektiv.
