Introduction

It's time to celebrate the Dewey Decimal System on December 10th – a day dedicated to honoring one of the most important library classification systems in the world! The Dewey Decimal System is an organizational tool used to classify books into ten broad categories that make it easier for librarians, teachers and students alike to quickly find the material they need. It was first developed by Melvil Dewey in 1876 and has since become an invaluable part of libraries all over the world. This day is not only a great way to recognize its importance, but also a good reminder to take advantage of all those resources our libraries have to offer!
