Reading history and reviews
Finished in 2006
This is a fascinating book, completely unlike any previous O'Reilly book that I've read - instead of hard-nosed technical information this is a wide-ranging meditation on the web and it's "leakage" into the real world of physical objects, all held together via the theme of "findability" and "findable objects". I think that this book is more about questions than answers - it is about possibilities, and makes you think "what if?". It touches on so many different ideas that I sometimes had to stop until I could get to a computer in order to look up some of the references, and the sweep of the references is excitingly wide (I was fascinated that references kept coming up to books that I was planning to read next). And I've never had so many people ask me about a book that I was reading just from seeing the cover.
I have started a page of links from the book.
