Page markers are small tools used to indicate specific locations in a book or document. They can be made from various materials, such as paper, plastic, or fabric, and often come in the form of sticky notes, flags, or bookmarks. Page markers help readers quickly find their place or highlight important sections for future reference. In addition to traditional bookmarks, digital page markers are available in e-readers and apps, allowing users to save their progress or mark significant passages. These tools enhance reading efficiency and organization, making it easier to revisit key information in texts like novels, textbooks, or research papers.
