Libraries are amazing places where you can borrow books for free. The organizational system of subjects is called the Dewey Decimal System. Invented by Melvil Dewey in 1876, it is still used today in libraries all over the world. To find a book on the shelf, look for the Dewey Decimal Classification (DDC) number on the spine. The number will tell you what shelf the book is on. Organization of subjects in a library is important to facilitate ease of access to borrowing books. The Dewey Decimal System is an organization of subjects which caters to this purpose. It groups items on a shelf according to logical relationships between them. Different types of books are put in different places on the shelf. For example, books on a subject are placed in the same area, regardless of the author. Go to the library, get a library card, learn the system and explore the possibilities.
