Revealing: In the extra 'Library' scene, the book that Bean is given already has the loose pages before he has been at them with the knife. (At one point the pages get pushed forward a little bit, meaning that they're not fastened into the book.)

Continuity: Just when Mr. Bean's hiccups are over the guy sitting on the table with him takes his right hand up to the book and has his left lower arm is on the table. But after Bean hiccups again he suddenly has his right hand down again and his left hand on his book.

Revealing: Just before Mr Bean rips a page out of his book, there is already a tear in it just before he actually tears it, which is not visible in any of the preceding shots.

Revealing: When Mr Bean's book falls apart, he tries putting the book back together, and he holds one page up to the camera and it has a slight reflection as if it is glossy paper. As far as I know old books like the one Mr Bean had don't have pages like that. It's an obviously fake book.
