When notes are taken during a classified meeting, what specific annotation should be included?

When notes are taken during a classified meeting, including the annotation "Working Paper" is crucial because it designates the document's temporary and informal nature while still acknowledging its classified content. This term indicates that the notes are subject to further review and modification and should be handled according to the same security protocols as formally classified documents.

By labeling the notes as a "Working Paper," individuals handling the notes are reminded of the sensitive nature of the information, ensuring that it receives the appropriate level of protection and awareness throughout its lifecycle. This notation serves to inform anyone who may access the document of its status and the need for caution when discussing or dispersing its contents.
