Which entity maintains a list of properly cited source materials related to classification?

The correct answer is based on the specific roles within the framework of classification management. Derivative classifiers are responsible for utilizing already classified information and applying classification markings to new documents, based on established guidelines and prior classifications. They are trained to understand the sources of information that can be used, ensuring that any new materials they create are properly marked and cited according to existing classification standards. This responsibility includes maintaining a list of properly cited source materials related to classification, ensuring that the information is reliable and compliant with classification policies.

In contrast, original classification authorities focus on determining the initial classification of information, while public regulators typically oversee compliance and enforce laws and regulations without directly maintaining classification citations. Information security officers manage the broader security programs but do not specifically handle the documentation of cited sources in the classification process.
