Read more nonfiction in 2024 with a Dewey Decimal Reading Challenge!

The Dewey Decimal System uses a hierarchical structure of 10 classes and organizes library materials by discipline or field of study. The Dewey Decimal System is often regarded as an outdated, racist, & sexist system under our modern lens. However, for the purpose of this reading challenge, the system is a guideline to read beyond one's typical nonfiction horizons.

Any nonfiction book within each Dewey class counts!
