Dr. Jeff Schippmann and I have written a chapter about M. P. Follett to be included in a forthcoming book about "great thinkers" in Industrial/Organizational Psychology. The book is being published by Routledge, and should be available later this year. It's a short piece, and it speaks very favorably of her life and work. 

I doubt we can share it without the publisher's permission, but I will inquire.

Regards, M.D. Smalley
