Taking book notes without killing the reading

Heavy note-taking is the surest way to stop enjoying a book. Light note-taking is the surest way to remember it. The difference is where and when the notes happen.

The short answer

Take book notes in two moments, not continuously. During the book: a mark at the page — an underline, a tab, or a photograph of the passage — with the page number and at most a word. Ten seconds, then back to reading. After the book: ten minutes within a day of finishing, writing what it was about, three things you took, and where you disagreed. Notes taken this way cost almost nothing while reading and give you everything you will want in a year. Notes taken continuously — summarising each chapter, copying every quote — turn a novel into homework and are rarely reread.

  • Ten seconds at the page, ten minutes at the end.
  • Page number on everything.
  • Fiction gets lighter notes than non-fiction: passages and one line, not arguments.
  • Three takeaways, not a chapter-by-chapter summary.

Why does note-taking kill the reading?

Because it interrupts. Every time you stop to write a paragraph, the book's momentum resets and the voice in your head changes from the author's to your own. Do that every few pages and a novel becomes a text you are processing rather than a story you are in. Non-fiction tolerates it better, but even there, notes taken during a first read tend to record what the author said rather than what you thought, because you do not yet know what mattered.

Three methods, compared

Three ways to take book notes
MethodWhenCost while readingWhat you getWeakness
Margin marksAt the page2 secondsA map of your reading inside the bookStays in the book unless copied out; not for borrowed books
Capture at the pageAt the page5–10 secondsThe passage as text, with the page, searchableNeeds a phone within reach
Notes at the endWithin a day of finishingNoneWhat you actually thought, once you know what matteredNeeds the marks or captures to work from

The methods are not rivals. The first two feed the third: marks or captures during the book, thinking afterwards. What to avoid is the fourth method — the running commentary, a paragraph every few pages — which is expensive during and rarely reread after.

The ten-second rule

Any note taken during the book should take under ten seconds: an underline, a tab, a word in the margin, a photograph. If you find yourself writing a paragraph, you have found something worth a real note — tab the page, keep reading, and write the paragraph at the end when you can see it in context. This rule alone is the difference between readers who take notes for a lifetime and readers who take notes for a month.

1 Something stops you A line, a claim, a question. 2 Mark it — under ten seconds Underline, tab, or photograph the page. Page number always. 3 Keep reading The book's voice, not yours. 4 At the end: ten minutes One sentence, three takeaways, the passages, one disagreement. 5 A week later: two minutes Reread the notes. This is what makes them stick.
Five moments. Only the second happens while you read, and it is short.

What to record — fiction versus non-fiction

Notes for fiction and non-fiction
DuringAfter
FictionThe sentences that stop you; the scene you will want to reread; a character's name if you keep losing itWhat it was about (underneath the plot); one line on what you took; who you would give it to; reread — yes/no/when
Non-fictionClaims you doubt; passages that explain something; the one example that made it clickThe argument in one sentence; three things you took; where you disagreed; what you will do

Fiction needs less. A novel with a hundred marks is a novel you were not reading; five passages and a line at the end is plenty. Non-fiction earns more marks during and a proper page at the end, and the book notes template gives that page a shape.

How do you take notes on a book you can't write in?

Removable tabs while reading, then photograph the tabbed pages before the book goes back — or photograph as you go, so the passage is saved as text with its page and there is nothing to do on the last day. The separate guide covers the five methods for library and borrowed books.

Where should the notes live?

With the book, findable from its title in two years. A tracker with notes on each book, a notes app with a page per book, or the inside back cover of the copy you own. Notes filed by date are notes you will not find; notes filed under the book are the book's memory.

In Pensovo Photograph a page and the passage becomes a highlight anchored to that page, on any book. Add a word if you like. Write the end-of-book note from the finished screen; everything stays with the book.

Common questions

Should I take notes while reading fiction?

Lightly: mark the sentences that stop you and write one line at the end. Heavy notes turn a novel into homework and are rarely reread.

How do I take notes on a book without stopping every page?

The ten-second rule: an underline, a tab or a photograph at the page, and nothing longer until the book is finished.

What should book notes contain?

During: passages with page numbers. After: the book in one sentence, three things you took, where you disagreed, and what you will do or who you would give it to.

Is it better to take notes during or after reading?

Both, in different sizes: seconds during, ten minutes after. Notes written during a first read record the author; notes written after record you.

How do I take notes on a library book?

Removable tabs while reading, then photograph the tabbed pages before returning it — or photograph as you go so the passages are saved as text with their page numbers.

Where should I keep my book notes?

With the book — a tracker's book page, a notes page per title, or the inside back cover. Filed by date, they are lost; filed by book, they are the book's memory.
