What concept is used to identify how the new document was classified?

The concept of classification by compilation is relevant when determining how a new document has been classified because it involves assessing a document that is derived from multiple classified sources or a base document. When compiling information from various sources, derivative classifiers must analyze the content to ensure that the new document maintains the appropriate classification level based on the individual classifications of the originating documents.

In this context, classification by compilation focuses on the new document's composite nature, ensuring that it adheres to the rules and guidelines regarding the handling of sensitive information from various classified content. This concept is crucial in maintaining the integrity and protection of classified information when creating new documents that incorporate existing classified content.

Understanding how documents are classified upon compilation allows for accurate handling and safeguards against unauthorized disclosure, which is vital in a security context.
