There are only 6 scrolls discovered so far. The six scrolls are definitely used in the Test of Lord along with a translator item. Not sure if a different translator item is needed for the Whistling Fist quest.
The tome binder is not related to these scrolls; it is used with "a tome page" that drop off the same frogs that drop the binder.
