Mary,
 
Your response annys me, as have all the other faculty
who continue to try to educate folks on the net who
have asked legitimate questions regarding research leads.
Why spin such diatribe on us when you could just delete
the e-mail that you do not like?  There are fabulous
sources on ash trays, glass and ceramic insulators,
battlefields, etc. published by obscure outfits that
do not make it into libraries like Berkeley.  Instead
of beating on the amateurs and students, share in
the exchange..... treat the e-mail like conference cocktail
talk where no one has a library between the lounge and
the piano, but everyone has toughts on a good place to
look for things.  Sheesh!
