256 The primary purpose of preservation is indubitably beneficial and arguably strongly transformative: ensuring access to aspects of our cultural heritage for future generations, well past the limited term of copyright protection. Furthermore, responsible preservation is a necessary precursor for future scholarly use in a variety of transformative contexts, including criticism, commentary, and teaching. A broader, four-factor analysis further supports digital preservation: Its purpose is noncommercial and educational, the amount of the work used is appropriate to the purpose (preserving only parts of works would be unsatisfactory), the nature of the works will in many cases be scholarly nonfiction (although this may be less likely in the case of VHS tapes), and preservation in the absence of a suitable replacement copy has no negative effect on the potential market of the preserved work (indeed, preserving the work for posterity should have a positive effect, if any).

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.

PRINCIPLE:

It is fair use to make digital copies of collection items that are likely to deteriorate, or that exist only in difficult-to-access formats, for purposes of preservation, and to make those copies available as surrogates for fragile or otherwise inaccessible materials.

LIMITATIONS:
 * Preservation copies should not be made when a fully equivalent digital copy is commercially available at a reasonable cost.
 * Libraries should not provide access to or circulate original and preservation copies simultaneously.
 * Off-premises access to preservation copies circulated as substitutes for original copies should be limited to authenticated members of a library’s patron community, e.g., students, faculty, staff, affiliated scholars, and other accredited users.
 * Full attribution, in a form satisfactory to scholars in the field, should be provided for all items made available online, to the extent it can be determined with reasonable effort.
