Hi Anthony,
Here's a non-fiction book I haven't seen listed on the Nanotechnology in
Science Fiction list:
Nanotechnology: Molecular Speculations on Global Abundance
Edited by B.C. Crandall
1996 Massachusetts Institute of Technology
This is a great book for the layperson and I thoroughly enjoyed reading it.
If you need more info, jlmk.
Thanks for maintaining a great list!
