Quick Review:  Doin' Dewey

General Dewey Numbers (by 100's)

Join Bogey Bear and Fuzby as they talk about getting started with Dewey Decimal Numbers

To keep things simple, the inventor of this system, Melvil Dewey thought about what people are interested in and how we share information. He created a system of 10 main classes with 100 divisions and 1000 sections. 

This means there THOUSANDS AND THOUSANDS of Dewey numbers. Every topic you can imagine has its own number! The good news is that we don't have to memorize them all.

Let's review the main Dewey classifications so that we can get started looking around the library for the books we like to read.  We can also get ready to start our Dewey Challenge II!
