That novelization version makes Anakin dumber than he was in the movie. At least in the movie, without any mention of a "restricted section," Anakin sees Palpatine as his *only* resource for learning the Sith "secret to immortality," thereby giving him a reason to keep Palps alive. But by introducing another option, Anakin would have to be an idiot to keep Palpatine alive rather than turning him in and proving to be the Chosen One who led to the Sith threat being eliminated. Jedi Master rank a certainty at that point, and access granted to all those "restricted" secrets.
What's the point of introducing an obsession over being denied access to a "restricted section" if he only learns about it *after* Palpatine's talk at the opera? From that point, he's seeing that he had *two* options rather than just a single desperate reliance on Palpatine. One option requires keeping a Sith Master alive; the other option fulfills the Chosen One prophecy and grants Anakin his Jedi Master access. Choosing the first one makes Anakin either really stupid or just determined to join the dark side. How is that better?
It ends up making Anakin look even worse. This just keeps getting funnier.
