The ephemeral nature
of digital media presents a challenge for the long-term retention of
electronic records. Government, academia, and the private sector increasingly
recognize the barriers to ensuring that documents survive changes in
storage, computer hardware, software, and ever-changing formats. The
records must be maintained free from tampering so that they remain authentic
and able to stand for the facts reliably year after year over time.
They must be able to support growing amounts of e-commerce and e-government
activity.
The preservation
challenge follows three tracks:
- intellectual
preservation--addressing the authenticity and integrity of the information
as originally recorded and stored;
- media preservation--addressing
the media on which the information is stored such as tapes, disks,
optical disks, CD-ROMS, etc.; and
- technology preservation--addressing
strategies such as migration and emulation strategies for helping
digital objects persist over time.
Whatever the system,
preservation measures require a closely audited, well documented, and
constantly updated system. Many researchers (Berthon and Webb, 2000;
Dollar, 1997; Duranti, 1995; and MacNeil, 2000) continue to explore
these challenging issues in digital preservation.
