Gibson is the master of subtle melancholy and nostalgia. His non-fiction is idiosyncratic collection of book introductions, random musings, and half-aborted magazine articles. There are motifs here: memory, technology, Japan, and the place where writing comes from, but no theme. It's a melancholy and nostalgic collection, and Gibson himself comes off as a very strange and slightly sad man who managed to resonate to the fears of 1984 and produce Neuromancer, and since then has occasionally re-opened the door to that place, but not, mostly in this collection.

This is not an essential book, but it's an interesting piece of cyberpunk nostalgia, and nobody turns a phrase like William Gibson.
