There were protests at the weekend against the UK's government's rules brought in last November, banning the sending of small parcels to prisoners in jails, effectively preventing books being sent through the post.
The government say that library facilities will still be available to inmates but the measure smacks of an infringement of civil liberties. It also seems to do little for morale and impedes any likelihood of rehabilitation. What message does this send about books (or prisoners) that they can be treated in this way? Effectively banning books, or at the every least making the provision of books a privilege that can be withdrawn, is a sign of an oppressive regime. I would encourage you to add your voice to this protest.
