Good luck to them. But, somehow, I don't think someone such as IDG Books Worldwide is going to make a mint publishing Knowledge Management for Dummies. Because, just like artificial intelligence methodologies, nobody has figured out how to build a sustainedly profitable business case around it. There's a big difference between the business of knowledge management and the knowledge management of business. Knowledge management isn't catching on in America and won't in the near future because most organizations aren't prepared to pay a premium for a methodology that they feel they should be doing anyway.
Artificial intelligence is a nifty technology but a lousy business platform.
Similarly, knowledge management is a perfectly decent set of methodologies that simply can't command top dollar in an increasingly competitive marketplace. But, frankly, these enterprises expect their managers to handle those tasks. Of course not. That isn't what firms pay for. And they aren't going to pay for knowledge management.
