This specific location within a large volume often signifies a key reference point for a particular concept, exercise, or piece of information. For instance, a textbook might use this type of designation to direct readers to a specific chart, a collection of stories might feature a pivotal passage on this designated location, or a guidebook could highlight a crucial instruction set at this point.
Locating specific information quickly and efficiently is essential for effective learning and problem-solving. Precise referencing, through a combination of page number and volume identifier, allows for clear communication and shared understanding amongst users. This precision minimizes ambiguity and saves valuable time. Historically, such detailed referencing has been crucial for navigating extensive written works and ensuring consistent interpretation across different editions and printings.
