  The Dewey Decimal System is a system used to classify books by grouping them in 10 different categories.  The person who developed the Dewey Decimal System was Melvil Dewey, a great librarian.   
    Most of the books in the library that have Dewey numbers are non-fiction books, such as books about machines, earthquakes, pets, cookbooks, and art.  They are books about real things or ideas.  Some books, such as
literature, plays, or  poetry, that are not real have Dewey numbers.  At Lakeview Middle School, all fiction books are catalogued and shelved without numbers because they are not true or real stories, although some of them may be realistic fiction
 
  Below is a chart showing the ten different categories of the Dewey Decimal System.  When these books are shelved, they are placed in numeric order first, and then alphabetic order.  Alphabetic order is used when more than one book has the same Dewey number.  For example, the book entitled the Automobile has the number 629.22 CON, and the book entitled Building a Stockcar has the same number 629.22 but the letters after are DEB.
