I started keeping a reading journal in 2018, mostly on a whim. A friend had mentioned she wrote down a few lines about every book she finished, and the idea lodged in my brain like a song you can’t stop humming. I bought a plain Moleskine notebook, wrote the date and the title of whatever I was reading at the time, and scribbled a half-page of reactions. That was five years ago. I’m on my third notebook now, and the practice has changed the way I read in ways I didn’t anticipate.

This isn’t a productivity hack. I’m not going to tell you that journaling will help you retain more information or read faster or impress people at dinner parties with your encyclopedic recall. It might do some of those things, incidentally. But the real value is stranger and harder to quantify. Keeping a reading journal forces you to have a relationship with what you’ve read, and that relationship, like any other, requires attention.

The Forgetting Problem

Here is something embarrassing: before I started journaling, I could not reliably tell you what I’d read six months prior. I’d look at a book on my shelf and think, “Did I read this? I think I read this.” Sometimes the cover triggered a vague emotional memory, something like “I think this one was sad,” but the specifics were gone. Characters’ names, plot details, the particular passages that had struck me at the time: all evaporated.

This bothered me more than it probably should have. I was spending 15 to 20 hours a week reading, which is a significant time investment, and retaining almost nothing beyond a blurry impression. It felt wasteful. Not in a utilitarian, every-minute-must-be-optimized kind of way, but in the sense that I was having experiences I couldn’t revisit. Imagine going on a trip to a country you’d never been to, spending two weeks there, and then forgetting nearly everything about it within a year. You’d be frustrated. That’s what reading without any form of record-keeping felt like to me.

The science on this is pretty clear, by the way. Psychologists have known since Hermann Ebbinghaus’s work in the 1880s that memory decays rapidly without reinforcement. His “forgetting curve” shows that we lose roughly 70% of new information within 24 hours unless we actively engage with it. Writing about a book, even briefly, is a form of active engagement. It forces you to process what you’ve read rather than simply consuming it and moving on.

What I Actually Write Down

My system, if you can call it that, has evolved over time. In the beginning I tried to be thorough. I wrote summaries, character analyses, thematic observations. This lasted about three weeks before the effort started feeling like homework and I nearly quit the whole thing.

What I settled on is much simpler. For each book I record the title, author, date I finished it, and then I write whatever comes to mind. Sometimes that’s a paragraph. Sometimes it’s half a page. Occasionally, when a book really gets under my skin, it’s two or three pages. There’s no template. I don’t rate books on a scale. I don’t try to be balanced or fair. I just write honestly about what the book did to me.

This matters more than you’d think. When I go back and read my entry about, say, a novel I read in early 2019, I’m not getting a sanitized review. I’m getting the raw reaction of the person I was at that moment. “I couldn’t stand the protagonist but kept reading because I needed to know if the sister survived.” “The prose in the middle section felt lazy, like the author was tired.” “I cried on the train reading the last chapter, which was mortifying.” These are messy, personal, sometimes contradictory impressions, and they’re infinitely more useful than a star rating would be.

Some people prefer more structured approaches, and that’s fine. I know readers who track page counts, reading speed, genres, and all sorts of metadata. There are apps like Goodreads and StoryGraph that can do this automatically. My concern with over-structuring is that it turns reading into a metrics exercise. I don’t want to think about my “reading pace” while I’m immersed in a novel. I want to think about the novel.

Patterns You Can’t See in Real Time

One of the unexpected benefits of keeping a journal for several years is that patterns emerge. I can look back at my reading from 2020, for instance, and see that I gravitated almost exclusively toward nonfiction during the first six months of the pandemic. I wasn’t making a conscious choice to avoid fiction. But the journal reveals it clearly: from March to August of that year, I read almost nothing but history and science. My brain apparently needed facts more than stories during that period.

I can also see my taste changing over time. In 2018, I was reading a lot of contemporary literary fiction, the kind that gets longlisted for major prizes. By 2021, I’d shifted toward older works, mid-century novels and pre-war nonfiction. Was this a response to something? A natural evolution? I’m not sure, but without the journal I wouldn’t even know it had happened. We’re bad at perceiving gradual change in ourselves. The journal provides a record that our memories can’t.

I’ve also noticed patterns in what I respond to most strongly. I tend to write the longest entries about books with complicated, morally ambiguous characters. Short entries usually mean the book was fine but forgettable. When I skip the entry entirely (which has happened maybe four or five times), it’s always because the book annoyed me and I didn’t want to spend another minute thinking about it. Even that absence is information.

The Rereading Question

Rereading is one of those topics that divides readers pretty sharply. Some people never reread anything, there are too many new books waiting. Others have a small collection of favorites they return to every few years. I fall somewhere in between, but keeping a journal has actually increased my rereading, and here’s why.

When I flip through my old entries, I sometimes encounter a book that provoked a strong reaction at the time but that I’ve since almost completely forgotten. The entry will describe something I found compelling, a particular scene or argument, and I’ll think “I don’t remember that at all.” That’s a signal. It means the book affected me enough to write about at length, which suggests it might be worth revisiting now that I’m a few years older and reading with different eyes.

I reread Marilynne Robinson’s Gilead this way. My 2019 entry was a full page of enthusiastic, slightly confused admiration. Reading it again in 2022, I found a completely different book, or rather, the same book that I was now equipped to understand differently. The journal entry from the first reading became a fascinating comparison point. I could see exactly what I’d missed, what I’d overvalued, and what had affected me both times.

This is something that Goodreads and similar platforms can’t really give you. They can tell you when you read something and what rating you gave it. They can’t tell you what you were thinking and feeling. That texture, those specifics, only exist in the journal.

Physical vs. Digital

I journal by hand in a physical notebook, and I realize that makes me sound like someone who also churns their own butter. There are perfectly good digital alternatives. Day One, Notion, a plain text file, a dedicated note in your phone. The tool doesn’t matter nearly as much as the habit.

That said, I find that writing by hand slows me down in a way that’s useful. When I type, I tend to compose, to edit as I go, to worry about phrasing. When I write by hand, I just get the thoughts out. The result is messier and more honest. Your mileage will vary. If you hate your own handwriting or never carry a notebook, a digital system will work just as well. The point is to write something, anything, about the books you read.

One argument for digital is searchability. I can’t search my handwritten journals without physically flipping through them, which is simultaneously annoying and pleasurable. Digital journals let you find every book about a specific topic, every mention of a particular author, every time you used the word “boring.” Some people find this extremely useful, especially if they write about books professionally or want to track specific reading goals.

I’ve considered switching to digital several times and always decided against it. There’s a physical pleasure in the notebook that I’m not willing to give up. Seeing the ink change (I use different pens), noticing where my handwriting gets cramped because I was excited and writing fast, feeling the weight of a full journal. These are sensory experiences that a database can’t replicate. But I want to be clear: this is a personal preference, not a prescription.

Journaling Changes How You Read

Here’s the thing nobody warned me about. Once you start keeping a reading journal, you read differently. Not dramatically, not in a way that ruins the experience, but in a subtle shift of attention. You start noticing things you want to remember. A particular metaphor. A structural choice. A moment where the author did something unexpected. Part of your brain is always slightly aware that you’ll be writing about this later, and that awareness makes you a more attentive reader.

I used to read the way I watched television: as a passive consumer, absorbing content and letting it wash over me. Journaling turned reading into something more like a conversation. I’m engaging with the text, pushing back against it, asking questions. “Why did the author end the chapter there?” “This argument seems to ignore a major counterpoint.” “The voice in this section feels different from the rest of the book, almost like it was written at a different time.” These aren’t thoughts I would have had before, because I wasn’t in the habit of articulating my responses.

Some readers might worry that this analytical layer would diminish the emotional experience. I’ve found the opposite. When you’re paying closer attention, the emotional highs hit harder. You notice the craft behind a devastating scene, and that awareness doesn’t reduce its impact. If anything, it amplifies it. You’re appreciating the book on two levels simultaneously: as an experience and as a made thing.

The Social Dimension

My reading journal is private. I don’t share it, I don’t post excerpts online, and I’d be mortified if anyone read some of my pettier entries. But even a private journal has a social function, in the sense that it’s changed how I talk about books with other people.

Before the journal, my book recommendations were vague. “Oh, it was really good, you should read it.” Now I can be specific. “The first hundred pages are slow but stick with it because the second half is extraordinary.” “If you liked X, you’ll love this because they’re both doing interesting things with unreliable narrators.” “Don’t read the reviews beforehand; the less you know, the better the ending hits.” This specificity makes me a better recommender, and my friends have noticed. I get asked for book suggestions a lot more than I used to.

It’s also improved my contributions to the book club I attend. Instead of showing up and saying “I liked it” or “I didn’t like it,” I arrive with actual observations. I can point to specific passages, reference specific structural choices, articulate exactly what worked or didn’t. This doesn’t make me the smartest person in the room (far from it), but it does mean I’m more prepared to engage with the discussion in a meaningful way.

Getting Started Without Overthinking It

If you’ve read this far and you’re considering starting a reading journal, I have one piece of advice: make it as easy as possible. Don’t buy an expensive journal with “Reading Log” embossed on the cover. Don’t design a template with fields for genre, page count, rating, and thematic analysis. Don’t look at other people’s meticulously organized reading journals on Instagram and feel inadequate before you’ve even started.

Get a notebook, any notebook. The next time you finish a book, open to a blank page and write what comes to mind. That’s it. If you write three sentences, that’s fine. If you write three pages, that’s also fine. The only rule is that you write something. You can figure out your system later, once you’ve established the habit.

The biggest threat to a reading journal isn’t doing it wrong. It’s not doing it at all because you’re waiting to do it perfectly. I know because I spent two years thinking about keeping a reading journal before I actually started one. Two years of lost entries that I’ll never get back. Don’t make that mistake.

Start with the book you’re reading right now. When you finish it, write down what you thought. Then do the same thing with the next one. In six months, you’ll have a record of your reading life that you’ll be grateful for. In five years, you’ll have something that feels almost like a diary, a record of who you were and how you changed, told through the books that accompanied you.

For what it’s worth, one of the books I wrote my longest journal entry about last year was The Last Archive, which surprised me with its emotional depth. Whether you end up journaling about our titles or someone else’s, the practice itself is the reward.
