In Marginalia, Mallett examines language in the social context or readership; in keeping with her interest in unsanctioned forms of communication, she created this body of work focused on the marginalia in books collected from the Vancouver Public Library. She first created a public artwork for the Vancouver Public Library, followed by a body of smaller photographic works (first exhibited at Artspeak in Vancouver.) In the Marginalia works, Mallett poses the library as an alternative archive, accumulating ‘damaged’ materials to uncover a parasitic system of communication, which coexists with the ‘host’ institution of the library.
