Language evolves over time. The words we use to refer to ourselves and each other change in response to new information, historical events, and social movements. Whenever we use a term to refer to a person or group of people in a museum exhibit, we are making a conscious choice. The choices we make reflect our values and our assessment of the appropriateness of particular terms in particular contexts. Service, Citizenship, and Civil Rights focuses on people who have experienced marginalization due to their membership in various identity groups in order to illuminate common themes.

The process of using language to describe and repair our world is ongoing.
