What is the purpose of footers in a document?

Footers in a document serve a crucial role in providing consistent and relevant information across multiple pages. Specifically, they are commonly used to display page numbers, which help readers navigate through the document effectively. Additionally, footers can include dates to indicate when the document was created or last updated, as well as copyright information to protect the intellectual property contained within the document. This organizational feature enhances the professionalism and usability of a document, ensuring that important reference information is readily accessible to the reader at the bottom of each page.
