Huge problem..let me explain...the printing of newspapers from that time is vastly differant than today....& the reason you can read some of the "bits" is because it has been kept away from constant handling & the sunlight exposure etc.
Once it is exposed to current handling & daylight - then the print will fade...as paper back then was not treated as like now & chemicals were very differant.
So bottom line is - it will need to be less handled & preferable away from any direct sunlight or reading lights as well.
I have had this situation & went to a Newspaper Company for their advice on preserving newspapers from 1915.
Cheerio,
