The statutory definition of records (44 U.S.C. 3301) includes all machine-readable materials made or received by an agency of the US Government under federal law or in connection with the transaction of public business. Agencies that allow IM traffic on their networks must recognize that such content may be a federal record under that definition and must manage the records accordingly. The ephemeral nature of IM heightens the need for users to be aware that they may be creating records using this application, and to properly manage and preserve record content. Agency records management staff determine the record status of the IM content based on the overall records management policies and practices of their agency.
