Documentation is the process of gathering and organizing information about a work, including its condition, its contents, and the actions taken to preserve it.

An installation may consist of numerous elements and be composed of various materials other than electronic media. It is therefore crucial to document all the components of the work, including its behavior, as soon as it becomes part of a collection. Describe the work's media components as well as the equipment that enables its presentation. It is also important to document the physical space and environment where the work is installed. In this sense, a conservator should treat a media installation as a special kind of sculpture. Each part is equal to the whole.
