The Uzumaki sword might have the power of sealing. The Uzumaki clan was known for their sealing techniques. So, it's possible that the sword can be used to seal away powerful enemies or even seal away dangerous jutsu. It could also have the ability to cut through powerful defenses. Maybe it has some sort of special chakra edge that can break through barriers that are otherwise difficult to penetrate. Additionally, it could have a connection to the Uzumaki's life - force, allowing Naruto to draw on some of that power in times of need.
Perhaps in this fanfiction, the secret library is guarded by some sort of magical or powerful entity. Naruto, being Naruto, would try to befriend it first.

Naruto might also be interested in books about the Akatsuki. Since they are major antagonists in his world, learning more about their motives, members, and plans could help him in his fight against them. He could study their past actions and try to predict their future moves.
