The room-si­zed in­stal­la­ti­on "small en­viron­men­tal li­bra­ry" con­sists of al­most 200 books from va­rious are­as of bio­lo­gy, which ha­ve be­en bla­cke­ned, glued and ma­de un­re­cognisa­ble with bi­tu­men-ba­sed un­der­bo­dy pro­tec­tion from the au­to­mo­ti­ve sec­tor. On­ly the small en­viron­men­tal li­bra­ry's own sys­tem re­ve­als the con­tent of the books. Di­vi­ded in­to the are­as of zoo­lo­gy, bo­ta­ny, bio­topes and land­scapes, bio­lo­gy and fun­gi, the books ex­press the power­less­ness over the loss of bio­di­ver­si­ty and na­tu­ral land­scapes. In­spi­red by the work "Volks­zäh­lung (Cen­sus)" by An­selm Kie­fer from 1991, the small Um­welt­bi­blio­tek is al­so in­ten­ded to sym­bo­li­se the failu­re of a so­cie­ty.
