Explanation

The Dewey Classification system is a classification system that was created in 1876 by Melvin Dewey. This is used in libraries based on the classification of books in a hierarchical manner. In the first level, also called summary, we can find ten main classifications of books, each with specific topics that deal with topics more generally; in the second level there are ten classifications for each classification found in the summary and the topics begin to deal more specifically with the topics of its summary. This pattern continues producing during more sublevels that allow establishing a great variety of classifications.
