Cortman Office Books is a loot table in Project Zomboid Build 42. The game rolls it 4 times when it fills a container, picking from 9 entries.
Chance is each entry's weight as a share of the whole list, per roll.
The most common entries are Leatherbound Book, First Aid I: "A Scouts Injury Guide", Phonebook, First Aid II: "Bandaging and Suturing", First Aid III: "Emergency Paramedics Manual".
Figures on this page are read from the Build 42 game files (42.22, November 2026). Chances are relative weights inside each loot table, not exact drop rates. Your game is the final word: if it disagrees with us, tell us and we will fix the page.
