Thank you for the kind thought, either to Jim or me, although I would defer to Jim because he gave the sources for our quotations.
My comment is not really an answer, but more of something to keep in mind. I have some old newspaper clippings. It is interesting that the older ones (latter half of the 1800s) seem less subject to becoming yellow and brittle than newer ones (early 1900s).
Another thought, it seems soaking the clipping for an hour seems a long time, although I have no experience to base this on. I would hope whoever posted this verified that the newspaper did not disintegrate or become too fragile to handle when wet.
I would get a color scan of the clipping before any chemical treatment. I think color would give a better result than black and white (or grey scale), but most scanners have the ability to do both.
