If you have to work with many pages, my first idea would be to do an automatic white balance correction (Colors > Auto > White Balance). With a little luck, it'll pick the "yellow" as white and the pencil as black. If that doesn't work out as you expect, do it manually with the levels tool, and make use of the three eye droppers (mainly the white one) in the "All channels" section. Getting to know the levels tool (or curves too for even more control) will help you with photos and scans anyway. Greetings, Daniel  http://docs.gimp.org/en/gimp-tool-levels.html
