Book

Books are a resource used to increase the Books need, which contributes to a population’s overall well-being. They are consumed when used, and the in-game tooltip describes beavers as eating the books while reading them.

Unlike physical goods such as food or logs, Books are an abstract need-satisfying resource rather than a stored material with practical building uses. They are part of the game’s broader goods and needs systems, alongside other resources that support survival, production, and well-being.

The production chain for Books begins with plants and ends with Books, but the intermediate steps are not detailed in the available source material here. What matters for colony planning is that Books are not a basic survival item: they are a higher-level need resource, so producing them is mainly about improving colony happiness and progression rather than keeping beavers alive.

Books are worth treating as a specialized output. A colony that is already stable on food, water, and housing can dedicate production capacity to them in order to raise well-being. Because they are consumed when used, any Book supply must be maintained continuously if the Books need is to stay satisfied.
