Dewey Decimal System Day is a day that marks the anniversary of the system's creation by Melvil Dewey in 1876. The Dewey Decimal System is a classification system for books that organizes them into ten main categories, each with ten divisions. This system makes finding a specific book much easier, and has been used in libraries all over the world for centuries.
Today, on Dewey Decimal System Day, we celebrate this system and all that it has done for libraries and literature. So take a trip to your local library today and celebrate Dewey Decimal System Day!
