I am curious about that too. Did taste shift in time and more with the 
digital tools we have today? How linear were the Lab a an b values along 
the tone range of analogue prints then. It would at least be nice to add 
the spectral plots of analogue B&W papers to SpectrumViz. Properly 
developed prints etc. That way we could have a more objective tool to 
compare the paper white color. I have only access to prints at least 30 
years old which is not a good source given OBA degradation etc.

Kodak and other companies must have archived spectral plots somewhere I 
think. I do have some old reviews of analogue B&W papers, must check 
what they have in information but do not recall even a Lab number for 
the paper whites. Last time I looked I was amazed that nobody in the 
seventies seemed to care about OBA content in the papers. Just one 
reference of OBA content.
