Media Archives: The desk flanked by two sets of microfiche readers in the room with the safe (it's the southern-most room) that is very close to the Children's Wing door. A battle with raiders may knock the book off the desk; check the floor if there is nothing on the desk.
To the west-northwest, in the ruins of a house occupied by raiders, on a shelf along the wall that is shared with a freezer filled with gore. It's next to the plates on the shelves. Note that a car exploding outside can knock the skill book off the shelf, making it very hard to find.
In the Meresti service tunnel, on the table near Robert's bed (the guy who guards the entrance to the Family gang encampment). While it is amongst owned goods, the book itself can be taken without a Karma penalty.

Entrance floor in a small storage room adjacent to the malfunctioning generator. Behind several yellow metal crates is an metal ladder on top of which is a Nuka-cola Quantum, book is under the ladder, but apparently inaccessible. Try to throw grenade inside ladder, blast may launch the book to a more accessible place.
Players who want to max out all skills should keep this bug in mind when collecting skill books.
PC The Vault 108 location of Tumblers Today is bugged. The best way to get this book is to place a lot of frag mines (usually 15) on the closest corner of the previous room. With a frag grenade as trigger, the book should be blown to an accessible position (see ). Another way to access this book is by wedging an explosive under the stepladder to move it. This last method is an extremely trial-and-error prone process, as the collision box for the stepladder will prevent you from interacting with it in any way, including the 'grab' button, despite being clearly visible and close enough for taking. On the PC version, it is straightforward to gain access to this book by simply deleting the stepladder. The console commands below will allow the player to get down behind the boxes and retrieve the book. If the player has not collected the Nuka-Cola Quantum on the stepladder, it will remain floating in the air after the ladder has been deleted. It is also possible to disable clipping in order to gain access to the book. [verified]
