The systematic assignment of a unique identifier to each leaf of a bound document allows for easy location of specific information and provides a sense of order and completeness. For example, a table of contents relies on this sequential designation to guide readers to relevant sections.
This seemingly simple process offers significant advantages. It facilitates clear navigation, enabling readers to quickly find desired content and cross-reference information. Furthermore, it contributes to a professional and polished presentation, enhancing the overall reading experience. Historically, this practice evolved alongside printing technology and became increasingly standardized as book production methods improved.
