This dissertation explores the ethics of conservation in regard to its honesty, focusing on the potential questions raised from the fire destroying the Mackintosh Library and its subsequent restoration. The research began as a project looking into honesty in conservation generally; its authenticity and what it reveals. However, the events of 23rd May 2014 changed the direction of this essay to focus on the Glasgow School of Art Mackintosh Building. Volunteering in the paper conservation department at the National Libraries of Scotland channelled the work into an exploration of libraries, more specifically the Mackintosh library and what a library’s purpose should be. How can conservation create honesty and authenticity? Is it an impossible task?
