List of books in The Sims 4

The Sims 4
In The Sims 4, bookcases start out with a selection of general books of various genres that do not influence a Sim's emotions nor skills. Additional books can be purchased by Sims in live mode by either clicking on any owned bookcase in the Sim's home to purchase books, or by ordering them online.

Emotion
Some books will put Sims that read them into a specific emotional state.

Skill
Unlike previous games, bookcases do not come prepopulated with any skill books. Skill books can be purchased from any bookshelf or computer: there is one for each skill in the game. Packs that add skills to the games all also add the additional skill books to the game.

Vampire Lore
These tomes function as skill books for the Vampire Lore skill, but are purchased from separate menus to the other books.

Other
These books can be found under the Children's section of the bookstore. They do not function as standard books, however.

Unobtainable Books
These books are not available for Sims to own. This is because they are either used for specific interactions, used by certain NPCs, or are completely unused.

Custom Books
Sims with Writing skill can write their own books on a computer, of which the title and description may be customised. Each genre of book that can be written has a variety of template titles that will initially appear in the text field when creating a new book. The default description for each of these template books simply says what genre of book it is.

General
These genres gradually become available to Sims as they level up their Writing skill. Dollhouse-genre books can only be created by children. Comedy books can only be written by Sims with high Comedy skill. Travel Guides can only be written by Sims with high Selvadoradian Culture skill.

Emotion
Sims can write their own emotion books, but only when they are experiencing that emotion themselves.

Skill Manual
Sims with the Professiorial reward trait from completing the Renaissance Sim aspiration are able to write custom skill manuals of any skill they are proficient in. Manuals for Baking, Herbalism, Parenting, Wellness, and Vampire lore cannot be created however, despite being skills that can be learned from books.
