Investigating the efficacy of interleaving materials in the preservation of plasticised PVC slip-cover notebooks in Yang Zhichao’s artwork Chinese Bible

Abstract

Plasticised poly(vinyl chloride) (PVC-P) is known to degrade rapidly and emit acidic gases and, as such, it is ideally stored separately from other materials. However, due to historic or aesthetic value, PVC-P book covers in paper-based collections cannot always be removed or replaced. There is currently a gap in the literature addressing strategies for storing PVC-P associated with paper materials. Prompted by a case study of the Chinese artist Yang Zhichao’s Chinese Bible (2009)—a performance installation artwork of 3000 notebooks including approximately 1000 notebooks with PVC-P covers—three potential interleaving materials (Mylar®, Hollytex® and buffered tissue) were tested to simulate u..
