Sink Project: Book Chute is a holodisk in the Fallout: New Vegas add-on Old World Blues.
It provides the activation code for the Book Chute in The Sink. However, it cannot restore all of Book Chute's functions.
This holotape contains the functionality profile for the Sink robotic assistant: "Book Chute."
The holotape can be found in Higgs Village's house#101, upstairs on the second room by a terminal.
