Ranganathan's Theory of Book Classification

Ranganathan's Theory of Book Classification is a systematic way to organize books based on their content. It uses a structured coding system called "Colon Classification," which assigns unique alphanumeric codes to topics, making it easier to find related subjects together. The idea is to group books logically by their subject matter, using a set of basic categories and modifiers, allowing for efficient cataloging and retrieval. This method helps libraries manage large collections by creating a flexible, hierarchical system that reflects the relationships between different fields of knowledge.
