Project Purity journals

Project Purity journals are the holotapes documenting the progress of Project Purity and are found behind your father's trail.

Project Purity journals
There are five entries in this series: 1, 3, 5, 7 and 8. (Others do not exist.) They detail James' initial efforts on the project.
 * Tapes 1, 3, and 5 are located in Rivet City in Doctor Li's personal quarters, which can be found on the Upper Deck directly across from a door to the Science Lab. They are on a table next to her terminal.
 * Tapes 7 and 8 are located in Jefferson Memorial sub-basement, the medical room. It is located just to the right once you go down the flight of stairs from the door to the gift shop.

Project Purity personal journals
There are seven entries in this series: 1, 2, 3, 5, 8, 10, better days, and an unnumbered tape (others do not exist). They describe James' recent attempts on the project after the extended hiatus. The unnumbered tape can sometimes be found as Project Purity Personal Journal 9 (Refer to 'Notes' at the bottom of the page).
 * Tapes 1, 2, 3, and the unnumbered tape are located on Dad's bedside desk in Jefferson Memorial sub-basement next to a derelict terminal.
 * Better Days can be found on a coffee table in the same room next to the door.
 * Tapes 5, 8, and 10 are found in Jefferson Memorial Rotunda, on top of a chemical mixing machine. They are pointed to by your quest marker in Scientific Pursuits.

Better Days
An additional, "personal" note is located alongside Project Purity personal journal (Zero) through 3, on a small table next to a bottle of Scotch. This tape has Catherine, the Lone Wanderer's mother, recording her stats on the project while being distracted by James. Ironically, she was in the middle of installing radiation filters, which the Lone Wanderer must repair during the storyline, in the control room when she was interrupted by James, the Lone Wanderer's father, for sex.
