This line often includes other information as well, such as:
* The name of the newspaper
* The date of publication
* The section or edition (e.g., "Sports," "Business")
It's essentially a quick reference point for readers to know where they are in the newspaper.
However, it's important to note that the term "folio line" is not universally used. Some newspapers may use different terms like "page header" or "running head."
