3. DEFINATION
Digital preservation refers to the various methods
of keeping digital materials alive into the future.
The need for digital preservation touches all our
lives, whether we work in commercial or public
sector institutions, engage in e-commerce,
participate in e-government, or use a digital
camera.

4. NEED FOR DIGITAL
PRESERVATION
• If the unique information objects that are
vulnerable and sensitive and therefore subject to
risks can be preserved and protected;
• If the preservation ensures long-term
accessibility for researchers and the public use;
• If preservation fosters the accountability of the
governments and organisations;
• If there is an economic or societal advantage in
re-using information ,or
• If there is a legal requirement to keep it.

5. NEED FOR DIGITAL
PRESERVATION
• Users’ perspective: User’s expectation is
always changing, yet users, specially research
scholars need both traditional documents and
electronic documents or old information and
current information.
• Institution’s responsibility: Libraries, archives
and other custodians have responsibility for
their any properties. So institution should plan
for digital materials including their maintenance,
preservation, and distribution.

10. REPLICATION
Keeping multiple copies – replication – is a long

valued for its ‘built in high redundancy and
protections against loss of information though theft
and disaster.
