Learn English – Can a book be divided in categories

synonymsword-choice

A book divided in several chapters/topics, can also be considered to be divided in categories (or have categories)?

Not sure if category can be used in this case, or if it should only be used in the context of category theory.

Books can be sorted or put in categories. For example, a book about Philippine cuisine written by Dostoyevski could be sorted into the categories "Cooking", "Russian author", "Philippines". But it would be sorted into each of these categories as a whole. You can't divide the book into categories. A category is a superordinate concept, while chapters is a subordinate one.
