Library

A library is a community lot and lot assignment in The Sims 3 that allows Sims to read books, but not to bring them home.

Gameplay descriptions
Every single book in the home world is here, with the exception of recipes, bait guides, guitar compositions, and books from The Sims 3: World Adventures destinations. If a player gets their Sim to write a novel, when it is completed it will often appear in the library. This may not apply to flops.

Libraries attract Sims with the Genius and Bookworm traits. They have lots of bookshelves, and usually have computers where Sims can practice the Writing skill.

As a lot assignment, libraries provide Power Study moodlet:

Libraries generate the following dark blue map tag in-game:



Willow Creek Archives
The Willow Creek Archives is the only library in the base game of The Sims 4. It has two floors containing bookshelves, computers, and public bathrooms.

Trivia

 * There is no proper library in Aurora Skies. Instead, there's a community lot Lend and Learn Library, but it's assigned as No Visitors Allowed. It's probably a mistake by the developers.
 * The library in Sims University is a shell building. Even though there appears to be many doors on the building, only one is a valid entrance to the shell.
