This is a really great piece of work, easily one of the best books on art history/art theory I have ever read. Morley writes clearly and lucidly, largely avoiding the dreaded 'artbollocks' and dense post-structuralist jargon; his knowledge of 20th century art history is commanding, and the choice of illustrative quotes and images is always spot-on. As well as the historical overview, Morley also offers some interesting observations that I think are original, particularly on the cognitive difference between reading and seeing. This acted as something of a bible for me when I was writing my dissertation, and I can highly recommend it either to the art student or the interested layman. The only flaw perhaps is the last chapter, which explores then-recent developments in digital and interactive media, which is already charmingly dated.
