The Appalachian Prison Book Project (APBP)—a grassroots, all-volunteer 501(c)(3) nonprofit organization—challenges mass incarceration by providing books and education to incarcerated people and by creating opportunities for volunteers and community groups to learn more about the legal and prison systems. Closely affiliated with West Virginia University, a land-grant research institution, APBP also provides internships and service-learning opportunities to undergraduates, graduate students, and law students and encourages interdisciplinary research. APBP sponsors lectures, conferences, performances, and other educational events related to mass incarceration.
