Cutter Expansive Classification

Cutter Expansive Classification is a system used to organize library materials and information. Developed by Charles Ammi Cutter in the late 19th century, it categorizes subjects into a hierarchical structure, allowing for easy retrieval. Each category is assigned a unique number, which can be expanded as new topics arise. This method helps librarians efficiently classify books and resources, making it easier for users to find what they need. Essentially, it’s a way to systematically arrange knowledge, ensuring that everything can be organized and accessed effectively.
