The Papers of the Exhibition (1977-2017) is a collaborative project between Bulegoa z/b and Azkuna Zentroa which will be carried out with several different public instances: a prologue in September 2016, and two international encounters in 2018 and 2019. The project aims to study specific exhibitions between 1977 and 2017. Each international encounter will focus on two decades. In the prologue, crucial, central concepts to the idea of the exhibition and its relationship to the idea of the rehearsal will be introduced.
