The library is in the lower right corner of the prison map. After turning off the lights at night, you can go to the lower right of the map and see the gate of the library, which can enhance your intelligence.

In Game Prison Break 2, there are two ways to improve intelligence, one is reading, and the other is using a computer. After finding the library, players can improve their intelligence by choosing reading. Another way is to surf the internet in the computer room during working hours and press the arrow to the work office. There is an NPC man sitting in a chair talking.

The work of the library is very simple. After entering the library, first take books from the bookcase in the upper room of the library and see whose name is displayed on the book, such as Paul's book. Then you have to find the front of Paul's desk, press the book in the item column, click the table and put the book on it.
