I've had, I don't know, four copies maybe, of this book over the years. One fell apart, dog eared and tattered, the others were lost or lent and never came home.
I guess it's testimony to how good it is that I keep replacing it.
That said, I think this is a love or hate kind of affair. If you are aiming to spark creativity, of any kind, it's very well worth your time picking up from the library and finding out which camp you fall into.
