The end of monopoly?

David Weinberger noted a few days ago (in a note from a conference on User Generated Content): "Then John Palfrey gave a talk about how the world and books look to those born into the digital age. To these digital natives, said John, the world doesn’t divide into online and offline; it’s all converged. They assume digital access. (YouTube is the #2 search engine, JP said.) They expect to be co-creators. They also give away too much information and need to learn to do for themselves the gatekeeping that used to be done for them. The opportunities are huge, JP said, for creativity, reuse, and making knowledge together. JP expects libraries will continue to become social spaces where we learn and explore together, and he expects physical books to persevere because they are so well engineered for knowledge and extended argument. [Personally, I'm not convinced of that. I think books may turn out to be an accident of paper. Check back in 30 years to see who's right.]" -- hrmm... that's interesting. I think. Libraries as social spaces... The end of physical books... OK, that's all well. But users as co-creators of the organization, representation, classification and meaning-making of books? How do we go about that; how do we get librarians to give up on their monopoly of being the profession that have the right to say what books in libraries are about and how we should think about them? When will it be the norm that I can add my categories, my thoughts, my comments to any book in any library catalog?
