Where should markings appear on microfilm or similar microform media?

Markings on microfilm or similar microform media should be placed in areas that are visible to the unaided eye. This is crucial because the purpose of these markings is to ensure that anyone handling the media can easily identify its classification level. Visibility is essential for maintaining security protocols and ensuring that individuals who come into contact with the material understand its sensitivity without requiring specialized equipment to view the markings.

By having the markings in positions that are readily accessible and identifiable, it reinforces the importance of safeguarding classified information and provides immediate acknowledgment of the content's status, minimizing the risk of accidental exposure or mishandling.
