  • 1. Understanding Dewey! Everything you wanted to know about finding materials in the library media center!

2. Libraries Begin

  • It was during the 1800s that libraries were beginning to spring up around the country.The printing press had made more and more books available to the general public, and more and more people were learning to read.

3. A Problem Evolves

  • Melvil Dewey was a very bright but frustrated librarian.As more and more books were added to his library collection, he found it difficult to locate materials.
  • Being a resourceful young man, he decided to create a standardized numbering system for classifyingnonfictionbooks in a library.

4. How Should Dewey Start?

  • Dewey wanted a system that put subjects into ten basic areas.(Thats because our numbering system is based on ten.)He wanted each book to have a specific number on the book spine so that the book would have a specific location on a library shelf.
  • If he used decimals with his base ten numbering system, he figured he could create detailed numbers for detailed subjects.

5. Dewey Classification 900s 800s 700s 600s 500s 400s 300s 200s 100s 6. And.

  • 000s
  • These are the basic ten sections of every library that uses the Dewey Decimal System.And, most libraries for schools and the public use this system.

7. Subjects ?

  • Dewey chose his ten basic subject areas by pretending to be a caveman.What kind of questions would the first man ask?
  • Dewey also wanted to be able to include subjects that were yet to be created due to future technology.(Smart guy, huh?)
