Associations for librarianship frequently speak out against inequities especially when related to the freedom to read. Prisoners are in a grey area, often ignored and overlooked by policymakers, despite potential impact of library services for incarcerated individuals. The field is also de-professionalized: candidates sans graduate degrees in library science frequently fill positions and correctional institution administrators often author policies on library service. Authors writing about prison librarianship cite the need to implement the public library service model despite the dichotomy between this model and practical implementations of prison library service. The reason for this dichotomy is apparent: practices in prison libraries violate many tenets of librarianship with the justification of maintaining order in correctional institutions. The gap between policy and practice continues to grow in prison libraries. Prison Librarianship: The Neglected Profession is an exploration of this gap in prison libraries in the United States. The author investigates state, national, and international policies on prison libraries, reviews literature on the topic, and describes partnerships between prison and public libraries. To determine adherence to policy results from a national survey and follow-up interviews are shared, which serve as narratives to describe what is actually happening inside.
