Taking a book published in 2007 called "Information Tomorrow" and reading it in 2009, it does feel a little bit dated. However, this collection of essays excellently sums up the direction of the library and information industry, from some of our more visionary leaders (at least, from the US).
Reading it now, it's more of a reminder and affirmation of many things that I already hold to be true, as a librarian - and whilst I haven't learnt much that is new from this book, it still reenforces ideas that are easy to be distracted from, or disillusioned with.
