Codices are rule books. Each faction gets one and through our the years they all contained fluff and lore. Some stuff you only ever get in a codex. Some stuff you only ever see in a novel. There is probably some cabin content that is exclusive to every single form the universe has appeared in.
Books are like the novels. Story books.
