How to Keep a Reading Journal (and What to Actually Write in It)

You finish a book you loved, and a month later you can barely remember why. The plot is fuzzy, the line that made you stop and reread is gone, and if a friend asks what it was about, you say "it was really good" and not much else.

A reading journal is a simple fix for that. It doesn't need to be beautiful or long. It just needs to catch a few things while they are still fresh. Here's what to write, a five-minute routine, and a few mistakes to avoid.

What is a reading journal?

A reading journal (or book journal) is a place where you write down your thoughts about the books you read: lines that stood out, how the book made you feel, questions it raised, and what you made of it in the end.

It differs from a reading log in one key way. A reading log records what you read (title, author, date, maybe a star rating), while a reading journal records what you thought about it.

Many readers keep both, and the log often becomes the first line of each journal entry.

What to write in a reading journal

If you're staring at a blank page, here are reading journal ideas that work for almost any book. You don't need all of them every time. Pick two or three.

• The lines that stopped you. A sentence you read twice, underlined, or wanted to send to someone. Copy it exactly, with the page number.
• Your reaction in the moment. Not a polished opinion, just what you felt: "I did not see that coming," "this character is driving me up the wall," "I had to put the book down for a minute."
• A one-sentence verdict. Force yourself to sum up the book in a single line. It's harder than it sounds, and it's often the most useful thing to reread later.
• Where and when you read it. On a train, during a hard month, on holiday, in the waiting room. Context is often what brings a book back to mind years later.
• What you'd tell a friend. Would you recommend it? To whom? "Good for anyone who liked X, but skip it if you hate slow starts" is more useful than a star rating.
• Questions the book left you with. Things you didn't understand, choices a character made that you're still arguing with, ideas you want to look into.
• How your view changed by the end. Did you start out bored and end up hooked? Did a character you liked turn out to be someone else? Noting the shift is one of the best book journal ideas, because it captures the actual experience of reading, not just the result.

A simple way to start

You don't need a system. Here's a small routine that takes about five minutes per book.

1. While reading: whenever a line stops you, mark it. Write it down or note the page. That's it, no commentary needed yet.
2. Right after you finish: before you start the next book, sit down for five minutes and write:
   • the title, author, and when and where you read it
   • your one-sentence verdict
   • the one or two lines you marked that still matter to you
   • one or two sentences of reflection: what you felt, what changed, or what you'd tell a friend
3. Optional, later: if a question from the book keeps coming back, add a note to the entry when it does.

Here's what a finished entry might look like:

Pride and Prejudice, Jane Austen
Read: March, mostly on the bus to work.

Verdict: A comedy about how badly we judge people on first impressions, including ourselves.

Line I marked: "I declare after all there is no enjoyment like reading!" (Caroline Bingley, ch. 11). Funny, because she says it while pretending to read and watching Darcy instead.

Reflection: I spent the first half agreeing with Elizabeth about Darcy, and then the letter made me realize I had been just as quick to judge as she was. I'd recommend it to anyone who thinks classics are stiff. It's sharper and funnier than I expected.

Question: Would Elizabeth have changed her mind without the letter, or did she need it in writing?

That entry took a few minutes to write, and it holds far more than "4 stars."

Paper or app?

Both work. The right choice is the one you'll actually keep using.

Paper is great if you enjoy handwriting, like a notebook you can flip through, or want a break from screens. The downsides: it's hard to search, you have to carry it, and quotes often end up on scraps of paper far from the rest of the entry.

An app helps in a few practical ways. You can search everything you've ever saved, lines stay attached to the book they came from, and you don't need a notebook on hand when a sentence catches you on the train.

Some people prefer a printable reading log as a middle ground: a one-page template for each book with spaces for the basics. It's a good option if you want structure on paper without designing your own layout.

Mistakes to avoid

• Trying to summarize the whole book. A plot summary is slow to write and rarely interesting to reread. Write about your experience of the book, not the book itself.
• Waiting for it to be perfect. Messy handwriting, half sentences, and spelling mistakes are fine. A rough entry you wrote beats a beautiful one you never got around to.
• Waiting until the end to write anything. By the last page, the moments from chapter three are already fading. Marking lines as you go makes the final entry much easier.
• Copying too much. If you copy whole pages, nothing stands out. Keep only the lines that truly stopped you. If you're not sure, leave it out.

Keeping your journal with Kept

If you'd like to try an app, Kept is a private reading journal built around the routine above.

While you read, you mark a line and it's kept with the book, so your favorite sentences don't end up scattered across notes and screenshots. When you finish, you add a reflection to the same place.

Kept is private. There's no feed, no followers, and no one else seeing what you write. It's free to start, and some features are part of a paid plan.

Frequently asked questions

How is a reading journal different from a reading log?

A reading log is a list of what you've read, usually with titles, dates, and ratings. A reading journal holds your thoughts: quotes, reactions, and reflections. Many people use a log as the starting line of each journal entry.

How often should I write in my reading journal?

There's no rule. A practical rhythm is to mark lines as you read and write a short entry when you finish each book. If that feels like too much, writing only about the books that moved you is fine too.

Do I need to write about every book I read?

No. Some readers journal every book, others only the ones that stayed with them. A short entry for a book you didn't like can still be useful, even if it's just one sentence about why.

Can kids keep a reading journal?

Yes, and it can be a nice way for them to talk about books. For younger readers, simple prompts work well: a favorite part, a favorite character, and whether they'd tell a friend to read it. Drawing a scene can count as an entry too.

What if I stop reading a book halfway?

Write about it anyway. A short note on why you stopped and how far you got can help you notice what doesn't work for you, and shows where to pick up if you return.
