Where To Find?
Five of the 11 books are located in fixed places. The other 6 are found randomly on book shelves inside buildings around the world.
Let's look at those five books first. Click on the map below if it's too small to read.
To zoom in. press Windows key and + key.
To zoom out, press Windows and - .
To quit the magnifier program, press Windows and Esc.
Those five books can be repeatedly taken.
After being taken, the 3D model of a prop book in the world does not despawn. It becomes non-interactive with that player, because a copy of that book is inside that player's inventory. That is, a player can only interact with that prop book if there is no copies of that book in the inventory.
So, if you want to bring back more copies for your team in multiplayer, hold Alt and left mouse click to drop every copy of that book from your inventory onto the ground to regain the ability to interact. When done with interacting for one more copy, drop that copy again. Rinse and repeat till you have the amount you need, and then press T to pick up all copies back that have been dropped on the ground.
On a side note, this is the same mechanic with those 6 main quest items.
