Informal Learning: Rediscovering the Natural Pathways That Inspire Innovation and Performance

Jay Cross has done a wonderful job of surveying the new field of knowledge work and what those of us in the 21st Century are doing to help people truly learn in groups and organization. He takes inspiration for the title from the work of the Institute for Research on Learning (now part of Far West Labs) that found that informal, social learning was the most powerful for bringing about real change and development. This work sparked the communities of practice movement among others. 

The book has a wonderful chapter on my work at National Semiconductor in the early 1990's with numerous graphics.
