The ministry of information used to screen all publications, music & films. I thought they had been abandoned. If they are still in excistance well, I think it is just a matter of policy that is not really important. Maybe the book you wanted is contraversial or not on their list and if they know it is for an individual, no problem.Have them clear the paper for you. If there does seem to be a problem, just explain that the book is for personal use.
