What is biography?
Biography is a factual story about a real person. If it is written by the person himself, it is called an autobiography. Under the biography call number “92”, the books are arranged according to the name of the person written about. The first letters of the biographee’s name follow “92” as part of the subject number. This subject number is then followed by the author code. A collection of biographies classes under the subject number “920”. Note that under the decimal classification system the numbers are sorted in decimal order. In other words “92” will follow everything classed as “91x.xxxx”, and before “920”.
