A book is not defined by being made of paper. Godin is pro-book but recognizes that the future of the book is as a digital file.

I don't think anyone is arguing that there is a continuing role for librarians who act as archivists of valuable paper books. But that number of librarians is vastly less than the number currently in existence.

Librarians who refuse to give up paper books are like record shops who refused to give up vinyl. Sure, a few will stick around--but the vast majority will have to move on.
