The attached photo is a raw scan of a page from 1970s word processing: paste together corrected paragraphs with mucilage glue. After 30-40 years the glue has turned brown.
How can I correct his in Lightroom? I'd like to minimize the browning due to the glue while retaining the quality of the typewritten text.
Since this is a raw scan in color, I can do almost anything to filter out the browning. But, my attempts haven't proven very successful.
Any suggestions would be greatly appreciated.

To build on Bob's suggestion, you can remove most of the rest of the discoloration by setting Orange and Yellow Luminance to +100 and Saturation to -100:
And you can make the text a little more crisp by increasing Basic > Clarity to +25:

This was about 2 minutes in Lightroom using the masking brush with Auto Mask turned on and just increasing the exposure of the areas to turn them white. You could do a LOT better if you took more time and effort. The file is small and I think a large scan would work a lot better. I set the brush to MAXIMUM size and just had to do about 8 to 10 clicks to chose 4 areas.
