Dewey Decimal Day

Dewey Decimal Day is celebrated annually on December 10th to honor the birthday of Melvil Dewey (1851–1931), the creator of the Dewey Decimal System. This system revolutionized library organization by providing a standardized way to categorize books and make them easier to locate.

What is the Dewey Decimal System?

The system classifies books into 10 broad categories, each represented by a three-digit number (e.g., 500 for Science). These categories are further divided into subcategories, creating a hierarchical structure for organizing knowledge.

Ways to Celebrate Dewey Decimal Day:

  1. Visit Your Local Library: Explore how the Dewey Decimal System is used to organize books and discover something new in a category you don’t usually explore.
  2. Learn About the System: Study the basics of how the Dewey Decimal System works and try categorizing a few books in your home.
  3. Appreciate Librarians: Thank your local librarians for their work and dedication to keeping knowledge accessible.
  4. Read a Book: Pick a book from a category you’ve never explored, like 700 (Arts & Recreation) or 200 (Religion).
  5. Host a Library Event: Encourage friends, family, or a community group to dive into library history or organize a scavenger hunt using the Dewey Decimal categories.

Dewey Decimal Day is a great opportunity to celebrate libraries, literacy, and the enduring legacy of Melvil Dewey’s work in making information accessible to all.
