>> Shelving is expensive. > That is so true. It is, but it's missing an even bigger cost. Walls are expensive. Housing space is expensive. Space for all our books has been a major consideration every time we've moved house. Crudely, I estimate $1-2/book for good shelving and $5-10/book for the space to put the shelves in, even taking into account the fact that the rooms whose walls you fill with books will have other uses too. Of course it depends where you live. I'm in a part of the UK where housing costs are heinous. In San Francisco or New York it would be even worse. In, say, North Dakota, I expect it's a different matter.
