It describes forms of preservation like local storage and initiatives like LOCKSS networks. Light archives allow broad access while dark archives have restricted access until triggered. Programs like LOCKSS, Portico, and CLOCKSS aim to provide long-term access. The document predicts preservation will follow print models over time.
