Libraries use the Dewey Decimal Classification (DDC) system to organise books in a systematic and logical manner. This system helps users easily locate books on library shelves.
Each book in the library is assigned a unique shelfmark (also called a call number), which is printed on the spine of the book. This shelfmark shows the exact location of the book.
