Introduction
Companies and public entities must retain records for a variety of reasons:
? To comply with laws and regulations that mandate records retention,
? To retain the “corporate memory” of activities and events that may be required to meet
ongoing business and historical needs, and
? To provide evidence in the event of an investigation or lawsuit in both regulated and nonregulated
industries.
Increasingly, electronic records are defined in laws and regulations as being equal to traditional
paper and micrographic records. This legal and regulatory evolution is recognition that the great
majority of contemporary fixed content business and public records are now “born” electronic or
converted to an electronic format. A second factor is that the volume of this fixed-content or
“reference” information is growing at 50-80% or so per year – a growth that is well beyond the
ability of an ever-expanding number of organizations to continue relying on manual intensive
paper and micrographic formats as official records.
