For years, preservation simply meant collecting. The sheer act of
pulling a collection of manuscripts from a barn, a basement, or a
parking garage and placing it intact in a dry building with locks on
the door fulfilled the fundamental preservation mandate of the
institution. In this regard, preservation and access have been mutually
exclusive activities often in constant tension. "While preservation is
a primary goal or responsibility, an equally compelling mandate--access
and use--sets up a classic conflict that must be arbitrated by the
custodians and caretakers of archival records," states a fundamental
textbook in the field (Ritzenthaler, Mary Lynn. Preserving Archives and
Manuscripts. Chicago: Society of American Archivists, 1993. p. 1).
Access mechanisms, such as bibliographic records and archival finding
aids, simply provide a notice of availability and are not an integral
part of the object.
In the digital world, the concept of access is transformed from a
convenient byproduct of the preservation process to its central motif.
The content, structure, and integrity of the information object assume
center stage; the ability of a machine to transport and display this
information object becomes an assumed end result of preservation action
rather than its primary goal. Preservation in the digital world is not
simply the act of preserving access but also includes a description of
the "thing" to be preserved. In the context of this report, the object
of preservation is a high-quality, high-value, well-protected, and
fully integrated version of an original source document.
