How to start a reading journal

Start with one page per book and four things on it: the dates you read it, a rating, the lines you want to keep, and a few sentences on what it was like. Everything else people put in reading journals is decoration. Those four fields are what you will actually reread years later, and they take about five minutes per book.
What to put on the page
Dates. Started and finished. These do more work than they look like: a year later, the dates are what place the book in your life, and they are the field that makes any kind of yearly review possible.
A rating. Give it while the book is fresh. Stars, a number out of ten, or your own scale; the value is in the comparison between books, so any consistent scale works.
Quotes. The passages you stopped on. Most readers find, going back, that this is the part of the journal they actually reread, and it is the part that is genuinely gone if you did not write it down.
Your reaction. Three or four sentences, written for you rather than for anyone else. What it did, what annoyed you, what it reminded you of. Not a review.
Paper or digital
A paper journal is better to sit with. Handwriting slows you down enough to think, the object accumulates in a way a database does not, and nothing about it demands your attention while you write.
A digital journal is better to search, and it is the one that survives. Typing a quote takes seconds against a minute of copying by hand, entries are findable in five years by author or by phrase, and there is no risk of losing the whole thing to a flood or a move. It also travels: a journal you keep on your phone is with you in the chair where you read.
The realistic split is that paper suits readers who finish twenty or thirty books a year and enjoy the ritual, while digital suits readers who finish fifty and want to search them. Plenty of people run both, keeping quotes on paper and the log itself in an app.
Keep the habit small enough to survive
Reading journals fail in the same way reading logs do: the entry becomes a chore, a backlog builds, and the backlog ends the habit. The defence is a small fixed format rather than discipline.
Write the entry the day you finish the book, in one sitting, and let it be short. An unbeautiful three-sentence entry beats an elegant one you never wrote, and a journal with a hundred short entries is far more useful than one with eight essays.
- Set a fixed format of four fields and do not add to it for the first three months.
- Write the entry the day you finish the book.
- Copy quotes as you read, not afterwards, since you will not find them again.
- Keep it to a few sentences unless the book genuinely demands more.
- Reread the last twelve months each December. This is the payoff, and it is what makes the next year of entries feel worth writing.
Write about the books you abandoned
A journal of finished books only is a curated version of your reading year. The abandoned ones are often more informative: they show you which recommendations you should trust less, and which kinds of book you keep buying and never reading.
Two sentences is enough. What you expected, where you stopped, and why. That entry saves you from picking up something similar in eighteen months.
What to do with it after a year
The point of a journal is not the writing. It is the December afternoon when you read the whole year at once and see what your reading actually was, which is reliably different from what you remember it being.
Look for the books you rated highly and never mention, the authors you returned to, the month where you read nothing. That is a better basis for next year than any goal number, and it comes free with a journal you kept in one place.
Questions
What if I miss a few books?
Leave the gaps and carry on. Trying to reconstruct entries for books you finished three months ago produces vague notes and usually kills the habit outright.
Should a reading journal be private?
It is more useful when it is, because a journal written for readers becomes a review and reviews are performed. If you also want to post about books, keep that separate from the entry you write for yourself.
