Writing a book note while it is still fresh

There is a short stretch of time after you close a book when it is still fully present. The characters are in the room, the argument is still turning over, and you could say, without looking anything up, which chapter mattered and why. Give it a week and most of that has gone. You will remember that you liked the book, perhaps a scene or two, and very little of what you actually thought.

A book note is a way of catching that stretch before it closes. It need not be long or polished. What follows is advice from the desk on writing one in the first hour or day after the last page, deciding what to quote and what to put in your own words, and, when a note seems worth it, turning it into a short piece others can read.

Why the first day matters

Finishing a book is an odd moment. You have just spent hours inside someone else's sentences, and your own response has been forming quietly the whole time, mostly unspoken. When you stop reading, that response is at its most complete and its least organised. It is also at its most honest, because you have not yet read what anyone else thought, talked it over or decided what you are supposed to think.

That last point is worth guarding. Reviews, discussions and summaries are useful, but they tend to overwrite a first impression rather than sit beside it. If you write your note before you go looking for other opinions, you keep a record of your own reading that nothing else can give you. You can always add to it later. You cannot get the first version back.

What to capture while it is fresh

A fresh note does not need to cover the whole book. It needs to hold what will otherwise be lost. A few prompts that work well, in roughly this order:

• One sentence on what the book is about. Not the blurb, but your version. If it takes three attempts to write, that is useful too.
• What stayed with you. The scene, example or idea you keep returning to in the minutes after closing it. Write down why, even if the reason is only a feeling.
• What surprised you or annoyed you. Disagreement fades faster than admiration, so set it down early, while you still remember the exact place it started.
• A question the book left open. Something it raised and did not answer, or answered in a way you are not sure of.
• Where you were. The date, and a line about your circumstances. It looks trivial now and becomes valuable later, especially if you ever come back to the book, as described in Rereading a book years later.

Write quickly, and do not reread the book while you do it. Flipping back through the pages turns a note into a summary, and summaries are the part you can always reconstruct. The note is for the part you cannot.

Quotations and your own words

Most readers finish a book with a handful of marked passages, and the temptation is to copy them all out and call that the note. A page of quotations feels productive, but it records what the author said rather than what you made of it. Months later it reads like a stranger's scrapbook.

A better habit is to be sparing. Choose two or three passages at most, the ones you would actually want to show someone. Copy each one exactly, with a page or chapter reference, and mark it plainly as a quotation. Then, directly beneath it, write a line or two in your own words: why this passage, what it does, what it connects to. The quotation is the evidence; the line underneath is the note.

For everything else, paraphrase. Putting an idea in your own words is slower, and that is the point. It is where you find out whether you understood it. If a paraphrase will not come, that is a sign to mark the idea as unclear rather than paper over it with the author's phrasing.

If you keep a slip-box, this is where the book note and the cards part company. The note stays whole, a record of one reading of one book. Any single idea in it that seems likely to be useful elsewhere can be lifted out onto its own card, rewritten to stand alone, as described in Keeping a slip-box: one idea to a card. Do that a day or two later, not in the first sitting. The first sitting is for getting it down.

Letting it rest, then reading it back

A note written in the hour after finishing is often warm, scattered and a little overstated. That is fine. Leave it for a few days, then read it back once with a pencil. Some lines will look obviously right. Some will look like enthusiasm that has not survived the week. Cross nothing out; instead, add a short dated comment where your view has already shifted. The note becomes a small record of the book settling in your mind.

This is also the moment to decide whether the note is finished. Most book notes should stay private, and that is no failure. They have done their job if they let you remember, years from now, what you thought. But now and then a note has something in it that wants to be said aloud, usually a single observation you have not seen made elsewhere.

Turning a note into a short public piece

A public book note is not a review. It does not need to assess the whole book, give it a verdict or tell readers whether to buy it. It can be much smaller: one reader's account of one thing the book did. That narrowness is what makes it readable.

1. Find the one thing. Look through your note for the line with the most energy, the question or disagreement or connection you keep coming back to. Build the piece around that and let the rest go.
2. Give the reader a foothold. Name the book and author early, and say in two or three sentences what it is, enough for someone who has not read it to follow you. No plot summary beyond what your point needs.
3. Use one quotation, well. Keep it short, cite the page or chapter, and spend more words on what you think of it than the quotation itself takes up. Our guidelines ask writers here to name their sources, and a careful citation also lets readers find the passage for themselves.
4. Say what changed. End with what the book left you with, even if it is only a better question. An open ending suits a short piece.

Somewhere between five hundred and nine hundred words is usually enough. If it grows much longer, it is probably turning into an essay, which is a good thing but a different job.

Keeping the notes together

Over a year or two, book notes add up to something no single one of them shows: a record of what you read, when, and how you responded at the time. Keep the private ones in one place, in the order you wrote them. If you publish some here, filing them in a drawer of their own and tagging them consistently gathers them on one topic page across the room; the features page explains how drawers and topics work, and long pieces get a contents list automatically.

Then put the book back on the shelf, with the note tucked inside the cover or filed nearby. The next time you finish a book, start the note before you reach for anything else. The first day is short, and it does not come back.
