I'm sure someone with a more lithe memory than mine can make a better list, but off the top of my head I can think of FIRST articles appearing in
Robot Magazine and
Popular Mechanics. Books would include Behind the Design (IIRC there's been one each year since 2006, by Vince W. and Steve S.). For a more local and intimate flavor, check out newspaper articles near regional events or the
FIRST in the News forum of Chief Delphi.
Good luck with your report and let us know how it goes! It would be awesome if you post a copy of it here for us!
