Gathering knowledge means organizing it to make it accessible and findable, a key mission of libraries. Yet, organizing every topic in the world into a single system is complicated. The two major library organization schemes, Dewey Decimal and Library of Congress, were created over 100 years ago and reflect the mainstream views of that time. These systems are built upon a white, male, cisgender, Christian, heterosexual, able-bodied point of view. This roundtable will explore the problems in how we organize knowledge, the implications of using systems built from whiteness, and how professionalism in the library field has protected these systems.
