If you want to organize books in a way that actually works, you first need to understand why they’re so hard to let go of. 

Books are not just objects. They represent knowledge, identity, and the person you hope to become. That’s why it’s easy to keep them, even when you don’t read them. However, when your collection grows out of control, it stops being a source of inspiration and starts becoming a source of stress.

The most common trap is keeping books for the person you want to be, rather than the person you are right now. You might tell yourself you’ll read them “someday,” but if they’ve been sitting untouched for years, that day may never come.

The KonMari philosophy is simple: Keep only what sparks joy. This means keeping books that make you feel happy, inspired, or useful today, not yesterday or "maybe" tomorrow.

And to begin, you need to see everything you own in one place.

Step 1: Gather All Books in One Place

This is the first step to see exactly what you’re dealing with. In the KonMari Method, you don't go shelf by shelf. Instead, you must gather every single book you own from every corner of your home:

• Take them off the shelves.
• Check your bedside tables and bags.
• Pull out those dusty storage boxes from the attic or under the bed.
• Put them all into one giant pile on the floor.

When you see all your books together, you begin to understand how much you actually own. You may also notice books you completely forgot about. Books you once bought with excitement but never touched again.

Step 2: Decide What Sparks Joy (Without Reading)

Now comes the work. Pick up each book, one by one.

The key principle here is simple: Touch, don’t read. 

If you start reading a few pages, your brain takes over. You start thinking, "Oh, this is interesting," or "I should really finish this chapter." Reading clouds your judgment and slows you down. Instead, focus on the physical feeling of holding the book. Does it give you a little "spark" of excitement? Or does it feel heavy and burdensome?

Trust your intuition. The moment you hold the book, you already have your answer. Don't overthink it.

Step 3: Let Go of What No Longer Serves You

This is often the hardest part. I’ve been through it myself, and you might experience the same.

When you start discarding, you may notice thoughts like:
“I want to keep all the books.”
“I haven’t even read this one yet.”
“This one is still brand new…”

Books carry emotional weight. We hold onto books because of unread intentions, the money we spent, or the emotional connection to the person who gave it to us. Because of that, letting go can feel uncomfortable. You may feel guilt, pressure, or uncertainty.

But ask yourself: Are you keeping the book, or the idea of who you want to be?

The key is simple: if it doesn’t spark joy, let it go. Focus on your feeling when you hold the book, not the content inside it.

Be Honest About "Someday"

Marie Kondo says, "Someday means never." If a book has been sitting on your shelf for years and you haven't opened it, you likely never will. It has already fulfilled its purpose by teaching you that you aren't actually interested in that topic right now.

Dealing with Uncertainty

If you are still stuck, you can use a “maybe box” and revisit it within one week. However, I don't recommend this for books. Books are the easiest category to delay decisions. A “maybe” pile can quickly turn into hidden clutter.

Instead, aim for a clear decision: Keep or Let Go. 

Trust your first intuition. You already know your answer when you touch the book. There is no need to overthink or justify it.

Before letting a book go, take a moment to thank it. Even if you never read it, it still had a role in your life. It may have taught you something about your interests, your limits, or your habits.

Step 4: Organize What You Keep

Once you finish decluttering, you can start organizing the books you decided to keep.

Begin by sorting them into categories. You might have categories like:

• Comics/Manga: Group by series.
• Fiction/Novels: By author or genre.
• General Non-Fiction: Science, History, Business.
• Personal Development: Self-help, Spirituality.
• Children’s Books.

You can adjust these categories based on your own reading habits.

After sorting, focus on how you store them:

• Store Vertically: It makes every spine visible and prevents books from getting "buried" at the bottom of a stack.
• Keep Similar Sizes Together: This makes the shelf look much neater.
• Spines Facing Out: Ensure you can read the titles easily so you can quickly find what you need.

The goal is simple: easy to see, easy to reach.

If you want, you can also make your bookshelf feel more inviting. Add a small plant or a simple decoration. Keep it minimal, but warm. A clean and calm space naturally invites you to read more.

Where to Give Away Books

Instead of throwing books away, consider passing them on to someone who can enjoy them.

You can donate them to local libraries, schools, or community centers. Many places are happy to receive books that are still in good condition.

Another simple way is through social media. Local groups or community apps make it easy to give books directly to people nearby who need them.

If you prefer something more direct, choose one or two people you know. Pick books that match their interests and give them as a gift. This works especially well with books you enjoyed.

This is not just about letting go of books. It’s also a simple way to connect with others. Sometimes, a small action like giving away a book can start a conversation, create new connection to others.

The goal is simple: Don’t overthink where they go, just make sure they go to someone who will use them.

What I Gained from Decluttering My Books

After I used this method to organize books, I noticed many small but meaningful changes.

My bookshelf became neat and easy to manage. I could find what I needed without searching. There were no more random books scattered around the house.

I also became more mindful when buying new books. I stopped buying books just because they looked interesting or useful “someday.” Instead, I only chose books I really wanted to read.

I also started to take better care of the books I kept. Because there were fewer of them, I appreciated them more.

How to Keep Your Books Organized Long-Term

Decluttering is only the first step. Keeping things organized is what really makes the difference.

After reading a book, return it to its place. Even if you haven’t finished it yet, try not to leave it on your desk or bedside for too long. This small habit helps prevent clutter from building up again.

Keep your category system consistent so you always know where each book belongs. When everything has a clear place, it becomes much easier to stay organized.

You can also build a simple daily habit: Take a few minutes each day to look around your space. If you see a book out of place, just put it back.

It’s a small habit, but over time, it keeps your space clear, calm, and easy to manage.

Ultimately, learning how to organize books is about more than just a clean shelf. It’s about being intentional with your time and your space. Your bookshelf should be a reflection of your real life, and the things you care about right now.

When you let go of the "ideal" version of yourself, you make room for the person you actually are to grow.
