1. A system for efficiently identifying unique email messages stored in organized email message stores, comprising:

  • a duplicate email message selector removing duplicate email messages containing substantially duplicative content from topically identical email messages logically extracted from a plurality of organized email message stores;

    a near-duplicate email message selector removing near-duplicate email messages containing content recursively included within another of the remaining email messages;

    a unique email message selector storing unique email messages comprising at least one of a email message storing a single occurrence of a given topic and a email message storing non-recursive content relative to each other such logically extracted email message and storing the unique email messages in a location within a store corresponding to a location within the organized email message stores from which each unique email message originated;

    a log identifying the relative source location of each unique email message and cross referencing any of the duplicate email messages and near-duplicate email messages relating thereto; and

    a cross-reference keyed collection identifying the relative source location of each unique email message and any of the duplicate email message and near-duplicate email messages relating thereto.
