A running head, also known as a running headline or running title, is a heading that appears at the top of every page or every other page of a document, book, or website. It usually contains the title of the work or the chapter, or a brief summary of the content on that page. Its purpose is to help readers quickly identify where they are in the document. Think of it like a navigation bar on a website, always visible and providing context. It enhances readability and makes it easier to find specific sections.
