Digital BW, The Print

Seems to me this was discussed here a while back, but since the
technology is moving so rapidly perhaps an update is in order.

I've been working with some architects on documenting buildings for
National Register nominations. I've been doing b/w darkroom prints, 
for that purpose but I've read such positive things about BO archival
qualities that I suggested this option to the architect. This morning
I got on the National Register website and was please to note they do
accept digital prints that meet the 75 year standard.

See: http://www.nps.gov/history/nr/policyexpansion.htm#further 

I didn't see the carbon BO process listed but would like to suggest to
the people at the Register that this be added to their list of
acceptable submissions. There is a statement in their policy that they
encourage people to submit new processes to them since they can't keep
up with all the changes.

Can anyone suggest how to approach the Register and make a case for BO
prints? I'm convinced, myself, of their archival properties, but I'd
to get my 'ducks in a row' before I contact them.

This is very exciting news, that the Register is moving in this
direction. I'm convinced we, here, have something positive to offer
them if we do it right.

Thanks all!
