What should be done when there are too many sources to fit in the 'Derived From' line?

When there are too many sources to fit in the 'Derived From' line, it is important to ensure that all relevant sources are acknowledged appropriately to maintain the integrity of the information. Citing "Multiple Sources" allows for a clear indication that the information is derived from various sources, and providing an attachment allows for comprehensive documentation of each source. This approach ensures transparency and enables anyone reviewing the classified material to verify the origins of the information without cluttering the main classification line. Acknowledging all sources is essential in maintaining proper accountability and traceability of the classified information. This method is especially useful in environments where accurate source documentation is crucial for compliance and security protocols.
