The library in the nearby college town is the same; however I was in their used book nook last week and they were so overstocked that they were practically giving stuff away: magazines 10/$1.00, paperbacks .25 or .50, hardbacks $1.00. Of course more expensive items were marked separately.
But I'm wondering if we've reached an e-Reader tipping point - are so many people clearing their shelves that the price of a regular used hard copy book is almost nil?
