Amazon's Family Library lets you share most Kindle books with up to four other adults and children under 13, but not all books may have access to
Amazon's Family Library is the built-in way to share Kindle books across your household. You can add up to four other adults and any number of children under 13 to your library. When you buy a Kindle book, you decide whether to keep it private or add it to the shared library — the person who bought it keeps a copy, and family members can read it on their own devices at the same time.
Not every book can be shared. Publishers set the rules for each title, and some authors or publishers restrict sharing entirely. When you go to buy a book, Amazon shows you whether sharing is allowed before you complete the purchase. If a book says "This title cannot be added to your Family Library," that restriction is permanent — no workaround exists.
Family Library works across Kindle e-readers, Fire tablets, and the Kindle app on phones and computers. Everyone reads from their own account and device, so there's no passing a single copy back and forth.
Key Takeaways
- Family Library requires all members to have Amazon accounts and live at the same address, and you can share with up to four other adults plus children under 13.
- When you buy a Kindle book, you choose whether to add it to Family Library at purchase time, and the original buyer always keeps a copy.
- Publishers control which books can be shared, and some titles have no sharing option regardless of when they were published.
- Each family member reads on their own device using their own account, so multiple people can read the same shared book simultaneously.
- If a book cannot be shared, buying separate copies is the only option — there is no way to override publisher restrictions.
Setting up Family Library with adults in your household
To create a Family Library, go to amazon.com, sign in, and navigate to Account & Lists (top right) → Your Account → Family Library. Click Create your Family Library. You'll be asked to confirm your address — all members must live at that address, and Amazon verifies this periodically.
To add another adult, click Invite adults and enter their email address. They'll receive an invitation and must accept it using their own Amazon account. Once they accept, they become a co-manager of the library. Both of you can add books, manage the library settings, and invite other people. If you later remove someone, they lose access to all shared books when ready.
Adding a child under 13 works differently. Click Add a child, create a child profile with a name and birthdate, and set up parental controls if you want to restrict purchases or content. Children don't need their own Amazon account — they use the child profile on a shared device or their own device linked to your account.
How to share a book you already own
If you bought a Kindle book before setting up Family Library, you can add it retroactively. Go to amazon.com → Account & Lists → Your Content and Devices → Books. Find the title, click the three-dot menu next to it, and select Add to Family Library. If that option doesn't appear, the publisher hasn't allowed sharing for that book.
Once you add a book to Family Library, it appears in the library section on every family member's device. They can read it to read offline or read it in the cloud. You keep your personal copy — removing a book from Family Library doesn't delete it from your library.
Sharing when you buy a new book
When you're buying a Kindle book on Amazon, scroll down to the Delivery & Purchase Options section before you complete the purchase. You'll see a line that says either Add to Family Library or This title cannot be added to your Family Library. If sharing is allowed, check the box to add it. If it's not allowed, you have no option to change that.
The person buying the book always gets a copy, regardless of whether you add it to Family Library. Sharing doesn't cost extra — you're not buying multiple copies. You're just giving other family members permission to read the one copy you bought.
What happens when someone leaves your Family Library
If you remove an adult from Family Library, they lose access to all shared books when ready. Any books they downloaded to their device will no longer open. If you remove a child profile, the same thing happens — they can no longer read any shared books.
The person who bought a book always keeps their personal copy, even if they're removed from the library. So if you bought a book and added it to Family Library, and then someone else is removed, you still have it.
If an adult leaves voluntarily, they can remove themselves from Family Library through their own account settings. They'll lose access to shared books but keep any books they personally purchased.
Books that cannot be shared and what to do instead
Some publishers restrict sharing on certain titles. This is most common with newly released books, self-published works, and some academic or professional titles. The restriction is set by the publisher when they upload the book to Amazon, and it applies to every copy sold — there's no way to request an exception or unlock sharing later.
If a book can't be shared and multiple family members want to read it, your only option is to buy separate copies. Each person gets their own copy on their own account. This costs more, but it's the only way to give multiple people access to a restricted title.
Before buying a book you plan to share, always check the sharing status on the product page. If you buy a restricted book by mistake, Amazon allows returns within seven days of purchase if you haven't read more than 10% of it.
Using Kindle Unlimited as an alternative for shared reading
Kindle Unlimited is Amazon's subscription service (about $12 per month) that includes access to over a million titles. Each person with their own Amazon account can have their own Kindle Unlimited subscription, but the subscription is individual — it doesn't automatically share across Family Library.
If multiple family members want to read widely without buying individual books, each person would need their own Kindle Unlimited subscription. This is more expensive than buying books outright if you only read a few titles per month, but it can save money if someone reads many books. Most Kindle Unlimited books can also be added to Family Library once you've borrowed them, so you get both options.
Frequently Asked Questions
Can I share Kindle books with family members who don't live with me?
No. Family Library requires all members to live at the same address, and Amazon verifies addresses periodically. If someone moves out, you'll need to remove them from the library. Long-distance book sharing isn't supported through Family Library.
What if I buy a book on my phone but want to read it on my Kindle e-reader?
The book automatically syncs across all your devices linked to your Amazon account. You don't need to do anything — just open the Kindle app or device and the book appears. If you added it to Family Library, it also appears on family members' devices.
Can a child in my Family Library buy books without permission?
Yes, unless you set up parental controls. When you create a child profile, you can require approval for purchases or disable purchasing entirely. Go to Family Library settings and click on the child's profile to adjust these controls.
If I remove someone from Family Library, can they keep reading books they downloaded?
No. Once removed, they lose access to all shared books, including ones they downloaded to their device. The books will no longer open. They keep any books they personally purchased on their own account.
Do I need to buy a separate Kindle device for each family member?
No. Multiple people can read shared books on the same device if you create separate profiles or accounts on it. Each person signs in with their own Amazon account, downloads the shared book, and reads it. You can also use the Kindle app on phones and tablets instead of buying multiple e-readers.
