Book return token is a recurring item throughout The Commonwealth of Fallout 4. They are most commonly received when the Sole Survivor returns an Overdue Book to a book return terminal in the Boston Public Library or East Boston Preparatory School (for which five tokens are awarded), but they can also be found in various other locations. The tokens can then be exchanged for a variety of prizes, the most notable of which is a copy of the Massachusetts Surgical Journal from a terminal in Boston Public Library.
A number of tokens can be found on the bodies of raiders guarding the Revere Beach station terminal location, and on the tables there.
