Did you know the secret behind finding library books easily? Read on…

Have you ever questioned why the library arranges its books in a particular way? Have you ever walked into your school library and wondered how the librarian keeps thousands of books organised? Imagine a giant puzzle where every book has a specific place, making it simple for you to find what you need. This magic trick is made possible by the Dewey Decimal System, used by libraries worldwide — including India! 

The day underscores the profound impact of the Dewey Decimal Classification (DDC), a system that has transformed libraries worldwide into accessible treasure troves of information.

According to Ms Vibhuti Katyal, Senior Librarian, Apeejay School, Saket, this day serves as a reminder of the importance of organisation and accessibility in the pursuit of knowledge. Melvil “First introduced in 1876, Dewey’s innovative system provided a universal framework that made locating books effortless, regardless of the size or location of a library.”By categorising books into ten primary classes, the system fosters uniformity and encourages a lifelong habit of learning. The Dewey Decimal System not only promotes order but also facilitates exploration. Books are the keys to wisdom, and the Dewey Decimal System is the map that guides us to them,” Ms Katyal shared.

The system is a way to organise books by subject using numbers from 000 to 999. Each number represents a different subject or topic, making it simple for librarians and readers to know where books belong. For example, if you love learning about space, you’ll find books about it under the number 520, which covers astronomy.

How It Works 

Each of the 10 main categories in the system has its unique number range. Here’s a quick look: 

000-099: General Knowledge (encyclopaedias, newspapers) 

100-199: Philosophy & Psychology (books about feelings) 

200-299: Religion (mythology, religious stories) 

300-399: Social Sciences (history, law) 

400-499: Language (dictionaries, grammar books) 

500-599: Science & Math (plants, animals, space) 

600-699: Technology (inventions, computers)  

700-799: Arts & Recreation (crafts, drawing) 

800-899: Literature (stories, poems) 

900-999: History & Geography (travel books, biographies) 

Why Is the Dewey Decimal System Popular? 

1. Standardised Organisation: The DDS provides a universal way to classify books, making it simple to adopt in multi-language and multi-subject libraries common in India. 

2. Ease of Use: The system simplifies book arrangement, making libraries more accessible for students and educators. 

3. International Compatibility: Many Indian libraries adhere to international standards for improved cataloguing and book-sharing due to its widespread use.  

“The Dewey Decimal System remains vital to libraries around the world. By grouping books into ten main categories, it offers a simple and intuitive way to find information, from science and technology to literature and history. This systematic approach encourages readers to explore new topics and fosters a love for learning,” the library enthusiast said in conclusion.
