The books in the library are on loan from the participants of SHOWING STYRIA at the Kunsthaus Graz. This is a collection of recommended books for the future. They reflect the range and diversity of the show’s themes. Texts inside the books explain why they were chosen. To make media easier to find in a library, they are usually organised according to certain systems: Main sections, subsec-tions and shelfmarks. The system used in Space04 is categorised according to hashtags. Each book has, depending on its hashtags, several possible locations. This principle has been applied not only to the library, but also to the exhibition and the digital catalogue, so creating links between the various areas and contents of the exhibition at the Kunsthaus Graz.
