The American barn / David Plowden.

Enhanced descriptions from Syndetics:

As an elemental part of our landscape and our history, barns evoke childhood memories for many of us, recollections of a simpler way of life. Regardless of their size or shape, their forms follow their functions. They are honest. They are beautiful. And they are rapidly vanishing. Across the land we see abandoned farms with barns falling down, being torn down, and only occasionally being converted to other uses. As urban sprawl eats up the countryside and food-producing Goliaths put small farmers out of business, the need for old barns has diminished. For most of his life as a photographer, David Plowden has admired and photographed barns. In recent years, as their disappearance accelerated, he made it his mission to document these beautiful structures, before they too are lost. The result is this beautiful book, his hymn to the American barn.
