This article provides a social work approach to reviewing the grey literature as part of a scoping or systematic review, one that incorporates attention to all layers of the social ecology through a person-in-the environment (PIE) framework. Little guidance exists on how to conduct a grey literature review specific to social work. Yet, consulting the grey literature, which often includes knowledge generated by practitioners and community members outside of academia, aligns with social work's commitment to social justice, integrity, and competence, because the grey literature contains case-specific and contemporary information about social work practice.While academic knowledge about ways to address injustices has value, it is often constrained by the broader influences of the neoliberal political economy, which emphasizes depoliticized market-based solutions to social issues and (re)produces inequities. Consequently, sole reliance on academic evidence compromises social workers' ability to fulfill their ethical commitment to integrity, competence, and social justice. We use a scoping review focused on the use of restorative and transformative justice as responses to sexual violence as a case study that demonstrates value of grey literature in social work. Our aim is to 1) demonstrate that grey literature should be an essential part of evidence-informed ethical social work practice; 2) recommend a social work approach to reviewing the grey literature that incorporates the person in the environment framework.
