I have books that are still in their shrink-wrap, bought because I know they are collectible, come heavily recommended by key taste-makers and will increase in value. I know people who buy books which they don’t even think of looking at, but pack away for some mythical future date of sale. I know people who buy two copies of the more precious books - one to look at, one to keep shrink-wrapped at a future date. It’s a despicable state of affairs and a horrible way of thinking.
