How the System works
The Dewey Decimal System is a method of organizing books by grouping similar subjects into 10 main classes and assigning each a number. Each of the 10 main classes is then subdivided further. It's not always easy to pinpoint where to look just by the names of the 10 main divisions. For instance, would you think to look for a book about your new puppy (636.7) or kitten (636.8) under "TECHNOLOGY"?! Here's a breakdown of some of the things you might find in each category:
- 000 Newspapers, Reference Tools, Libraries, Loch Ness Monster, Bermuda Triangle, UFOs
- 100 Logic, Ghost Stories
- 200 Religions of the world, Mythology
- 300 Politics, Government, Money, Law, Holidays, Fairy Tales
- 400 Dictionary, Thesaurus, Foreign Languages
- 500 Mathematics, Astronomy, Chemistry, Biology, Earth Science, Animals
- 600 Health, Pets Cooking, Transportation
- 700 Architecture, Drawing, Painting, Photography, Music, Sports
- 800 Poetry, Writing, Authors, Book Lists
- 900 Travel, Ancient Civilizations, US History, Countries
