Digital preservation

Definition and stakes

James S. Heller,  The Librarian's Copyright Companion (2012)

“ To justify the effort and expense of digital preservation, the works preserved will typically be unique, rare, or, in any event, out-of-commerce, and the library’s activities therefore will not be mere substitutes for acquisition of a new digital copy of the work. Works in obscure, near-obsolete formats present access challenges as well as preservation ones, but the same fair use rationales will apply. Works trapped in decaying and increasingly obscure formats will disappear completely without diligent work from librarians to migrate them to usable formats. ”

“ These take the same form as research libraries: if digital material is distributed to hundreds of computers at hundreds of libraries worldwide, then we militate against geographically local points of failure. One of the most well-known digital preservation mechanisms is called LOCKSS, which stands for ‘Lots of Copies Keeps Stuff Safe’, a name that embodies this principle. A green deposit of an article is just one further instance where that material is stored somewhere else, reducing the chance of a catastrophic single failure. This also explains why green is not just the opposite of gold. ”
