Digital BW, The Print

I have run across a couple of postings here where people 
refered to the "new revelations about silver print longevity".

Where can I read this published information? I'm just curious 
and am putting together a file of technical information on 
contemporary printmaking.

I have never heard this before visiting this site. I know Wilhelm 
told everyone years ago to  "avoid at all cost" black and white RC 
meda, primarily because of the quick fix and washing via 
automated processors assiciated with commercial output . But 
I've always known that rc black and white was never designed for 
permanence but rather speed. LIke the old saying, " are black 
and white rc papers archival" - answer " God, I hope not"

But I never knew there was new data about carefully processed , 
washed and toned silver prints. Interesting.
