It's an interesting book but is very much written / edited for an academic audience. What intrigues me about such work is that they are often used for quotes and discussions in other academic papers, but you wonder how many readers sit down and read them for pleasure.

Two books mentioned by previous posters which I really enjoyed reading were Geoff Dyer's The Ongoing Moment and Gerry Badger's The Pleasure of Good Photographs. Also Approaching Photography by Paul Hill, recently re-published. All books which I will look forward to reading again.
