Free access to books has dramatically improved the lives of incarcerated individuals, offering immense emotional and mental relief as well as a key source of rehabilitation. But as of last month, the Pennsylvania Department of Corrections (DOC) has decided to make such rehabilitation much harder. Going forward, books and publications, including legal primers and prison newsletters, cannot be sent directly to incarcerated Pennsylvanians. Instead, if they want access to a book, they must first come up with $147 to purchase a tablet and then pay a private company for electronic versions of their reading material - but only if it's available among the 8,500 titles offered to them through this new e-book system. Incarcerated people are paid less than $1 per hour. Most of the e-books available to them for purchase would be available free from Project Gutenberg. And nonpublic domain books in Pennsylvania's e-book system are more expensive than on other e-book markets. This policy, part of a larger trend of censorship in state prisons around the country, should alarm everyone. Not only does it erect a huge financial barrier to books and severely restrict content, it also ... severely damages an incarcerated person's ability to fully reenter society. Perhaps more alarming is that the head of the Pennsylvania DOC, Secretary John Wetzel, is president of the Association of State Correctional Administrators. If Pennsylvania's policies remain in place, other states are sure to follow suit.
