Citation justice is about recognizing the ways in which traditional, scholarly writing and publishing perpetuate the systemic oppression of marginalized groups, and privilege mostly white, male, voices. To practice citation justice means uplifting and centring BIPOC experts and voices, and ensuring that you don't contribute to the erasure of BIPOC expertise.
Andrea Eidinger's 2019 blog post "Cultivating a Conscientious Citation Practice" highlights the power and politics of citations, links to numerous other resources that explore the many issues that relate to citation justice and injustice, and provides an extensive list of suggestions for practices you can use in your research and classroom practice.

Before trying any of the following activities and assignment ideas, first have a discussion with students about why citing is a practice in academia, how it plays a role in tenure and promotion, how citing a source means conferring both authority and power to a person's research and ideas, and introduce issues relevant to your discipline (ie: under-citation of BIPOC scholars, female scholars, disabled scholars; over-citation of white, male, able-bodied, cishet scholars, etc).
