Chemistry journals

Usage
This is a quest item, used by Miles to harden your power armor in Fallout. The appearance in-game is identical to the Big Books of Science, so don't be fooled.

Location
The chemistry journals can be bought from Mrs. Stapleton in the Hub Library for 750 bottle caps.

Behind the scenes
The chemistry journals were also remade for Fallout Tactics (as a compilation of New England Chemistry Jorunal issues 778 to 800), but don't actually appear in the game.
