1. A method for indexing duplicate information stored in records, each record having a unique address, comprising the steps of:

  • generating a first value for a first particular record, the first value being derived from substantially all of the information of the first particular record;

    storing in an index the first value in association with a representation of the unique address of the first particular record;

    generating a second value for a second particular record;

    comparing the second value to the first value; and

    when the comparing step determines that the second value is equivalent to the first value, storing a representation of the unique address of the second particular record in association with the first value.
