Digital BW, The Print

While I checked the dates of first OBA and barite use in photo papers I 
came across an initiative of the Getty Foundation:

So if you still have old film and paper packages lying around you know 
what can be done with them. Related research articles can be found 
through that link too.

What I miss is a similar initiative for digital photography. Sure 
analogue photography is heading for bicentennial but digital prints are 
close to 30 years now. Some papers and inks are no longer produced but 
enough will still be stored by users and distributors that will be 
thrown away in the next decades.
