How to unlock: Talk with Daisy the merchant in the Goodneighbor location (M6,4).
- Go to Boston Public Library
- Return overdue book
- Explore the Library
- Clear the Library of Super Mutants
- Return to Daisy
During this quest you must return the book to the Boston Public Library and clean that location of supermutants. During the dialogue you can negotiate twice the payment from Daisy if you have high Charisma. There are two roads leading inside, but both seem to be almost the same - through the station (from the side of the building opposite to quest marker) or frontally, as the quest marker shows. In both places the door is locked with a second rank lock. If you cannot open it, you can use low Charisma to use the intercom, tell that you are a worker and guess the password.
Map which you see above is related to the side quest - finding the books that weren't returned on time. It also shows the location of the Intelligence Bobblehead.
- Book returning machine
- The book in the woman's toilet
- Three books behind the door, on the floor
- Book on the shelf, below
- Book in the library, on the desk
- Intelligence Bobblehead
Don't attack the robots inside. They aren't hostile. Go left and hide between them. After a while, supermutants will enter the building through the main entrance. Get rid of them. Robots will help you.
Behind the door at the end of the room you will find the Intelligence Bobblehead. The key to the locked container is lying on the desk next to the terminal, near the door.
If you want to complete the optional objective, you must return all the books that weren't returned on time. For each book you will receive 5 tokens. There are 6 books to find (+ the one from Daisy), which can give you total of 35 tokens. Other tokens can be found in bodies of dead enemies. You can also return here later when you will obtain more of them. The location of the books to return can be found on the map at the beginning of this chapter. You can obtain the Massachusetts Surgical Journal for collecting 50 tokens and using the machine's terminal.
Quest reward: experience, from 200 to 400 bottlecaps
