Whilst I tend to agree with you that libraries *ought* to be free resources I think the idea of having a rental pool of pure entertainment materials is a good one. I'd want to extend it to pure entertainment best seller books too I think - at least the multiple copies. Maybe have one free copy in each library but have the multiple copies that will later be sold off cheaply once the shine wears off be payable at a very cheap rate similar to what you describe. In the UK I think the cheap rate *could* be 1 UK pound, with concessions at 50p say for those who get concessionary prices (everyone on benefits and children, usually, IIRC).
