What purpose do annotations serve in copied and scanned documents?

Annotations in copied and scanned documents primarily serve to provide additional information or context that may not be captured in the original content. By including numbers, dates, and other relevant details, annotations help clarify the content and improve the organization of the information. This is particularly useful when referencing parts of the document later or when needing to track changes or important events related to the content.

In a practical setting, annotations contribute to better understanding and usability of the document, transforming it into a more informative resource for the reader. While enhancing image quality, adding visual appeal, or summarizing the document are all valuable characteristics in various contexts, the specific role of annotations in this case is to support the identification and organization of essential details.
