To read is not a fair use; it's an unregulated use. To give it to someone is not a fair use; it's unregulated. To sell it, to sleep on top of it, to do any of these things with this text is unregulated. Now, in the center of this unregulated use, there is a small bit of stuff regulated by the copyright law; for example, publishing the book - that's regulated. And then within this small range of things regulated by copyright law, there's this tiny band before the Internet of stuff we call fair use: Uses that otherwise would be regulated but that the law says you can engage in without the permission of anybody else.
