This is the first book-length study of prison libraries to provide a comprehensive overview of their history and to analyze their development in terms of the goals of correctional agencies and the values and traditions of librarianship. The author's introduction points out that in recent years new considerations have made it more difficult to clearly determine the value and purpose of prison libraries with respect to both the inmates who use them and the institutions of which they are a part. A heightened sense of professional consciousness in the library profession, expanded awareness of the uses of libraries, and changes in the laws and politics of criminal justice have all contributed to new ways of thinking about prison libraries, and have made a seemingly once simple matter complex.
