Preservation – to prolong the existence of library materials from physical and chemical deterioration and prevent the loss of content.
Digital Preservation- the management of digital materials over time, by using curation (management of data from creation), archiving (proper storage and access) and preservation (maintenance) strategies.
Digital Preservation Issues
Digital media lacks permanence – media changes and/or corrupts
Digital media depends on computers for readability
Multiple formats – preserve digital copies along the way
Born digital materials– websites like Cybercemetary
Digital Preservation Strategies
Develop better digital storage media
Refresh digital data – copying from one location to another
Migrate to newer/improved formats
WHEN THERE’S TROUBLE
Technical emulation- using technology to imitate the function of the computer system on which the digital materials were created
Digital Archaeology- Recreation of unreadable stored bits. on-going management of data from the point of creation.
