Review of the Dewey Decimal System.

100s - Who Am I? - Books About Us - Psychology . Since most people are most interested in themselves, Melvil Dewey started by creating a group for books that are about who we are. This means how we think and act. This section is numbered from 100-199.

200s - Who Made Me ? - Religion� After we think about ourselves, many want to think about how we got here. The next group that Dewey created is about religion and Myths. These books try to explain how people got on earth and why we are here.

300s - Who Is My Neighbor? The next thing that interests people are the others around us. Dewey knew there would need to be a groups of people to share information with. These are books about how people live, the things we do, and folklore.

400s - Language - How Do I Communicate With My Neighbors? If we have things to share with our neighbors, we need to be able to talk to them. This group of Dewey numbers is about languages, how we write, and grammar.

500s - What Will I Talk About? - Natural Sciences. Now that we know our neighbor and how to communicate, we need things to talk about. Dewey made this group for books about math and science.

600s - What Will I Do With Science? - Applied Sciences.� Now how can we use numbers and science? The next Dewey grouping is about how we use science in medicine and technology - APPLIED SCIENCE.

700s - Sports - Time For a Break! What Will I Do For FUN?� Dewey knew that we would also want to relax and have fun. This group is about arts, sports, and recreation.

800s - Literature:� Authors and Books That Make Me Who I Am. �Here we find important books we read, which we call literature. Famous authors and famous books are important, so Dewey gave them a special section in the Dewey Decimal System.

900's - History: How Did Everything Happen? In order to understand everything else, we need to answer these questions. Dewey created a special section for geography and history

000-099s - Everything Else - Room to Grow! Remember, Dewey lived a long time ago. He could never have imagined many of the things we talk and read about today. He knew this, so he created a special grouping for everything else that would come along. This includes topics such as aliens and software.
