Yesterday, I was very excited because the leader of the knowledge management community Dawenbert pointed out that most enterprise information or knowledge management results were poor than expected, because the information technician occupied dominant, if the book management expert also participated in, the effect will be better. This gives me a lot of gratification to re-recognize my professional. He also pointed out some limitations of book management experts. What I don't understand now is the core expertise of traditional library disciplines? This expertise should enable students graduated from library discipline to win a place in the knowledge and economic information society, rather than just in a mechanism in the library. Our social value is going out of the school, how should we reflect after going out of the library?
