Preservation of Installation Art

Preservation refers to the overall process by which the content of an item is saved and its long-term viability is ensured. With respect to installation art, the preservation assessment of all distinct components that make up an installation artwork should be done concurrently in order to maintain, as best as possible, the authenticity of the original piece. Thorough documentation of the original will inform your preservation methodology and process.
