Book

Books are normally stored in bookshelves, but Sims can put them down on most surfaces.

In The Sims and The Sims 2, all books were identical. Sims could use them to study mechanics or cooking, or to Read a Book (increasing fun).

The Sims 2 added the ability to study cleaning, and to write a diary.

In The Sims 3, the book system was overhauled. Skill books have three levels, and could be too easy - or too advanced - for Sims at other skill levels.
