* A copy of the California Civil Code: This book represents a glimmer of hope for Crooks, a way to understand the laws that govern the world and perhaps even find a way to fight for his rights.
* A tattered copy of "The Saturday Evening Post": This book provides Crooks with some entertainment and a connection to the outside world.
It's worth noting that these books are not just physical objects but symbols of Crooks' loneliness and yearning for connection. He values them greatly, and they provide him with a sense of solace in his isolated existence.
