Family Library lets you link your Amazon account to that of another adult in your household so you can easily share Kindle books, apps, and audiobooks across your Amazon devices and Kindle reading apps. Each adult chooses what they want to share: they can share all of their Kindle books, apps, and audiobooks, or, they can choose to only share individual titles.
电子书，有声读物，软件游戏APP皆可共享。
In order to use Family Library to share your content with another adult in your household, you must join a virtual household together. Members of a household include:
Two adults, each with their own Amazon account.
Up to four children. Child profiles are created as part of an adult’s account.
家庭成员可包括两个成人，和四个孩子。
