How to Read and Remember More Non-Fiction

Preview before you commit, skip freely, and use the two study techniques research rates highest: recall and spaced review.

Non-fiction asks more of you than a novel: no plot to carry you, and the whole point is to remember what you read. Most advice stops at "take notes." Memory research has better answers: trying to recall what you've read beats reading it again, and reviewing it a few times, spread out, beats one long review. Here's how to choose non-fiction you'll finish, read it efficiently, and keep what matters.

Read with a Question

Before starting a non-fiction book, write down in one sentence what you want from it: the problem it should help with, or the question it should answer. That turns you from an audience into an investigator, and it tells you where to pay attention.

It also gives you permission to stop. If you got what you came for by chapter six, the remaining chapters owe you nothing.

Preview Before You Commit

Spend twenty minutes finding out whether a book deserves the next ten hours. Read the introduction and the conclusion, scan the table of contents, and read the first and last pages of a chapter or two. Mortimer Adler, in How to Read a Book, called this inspectional reading, and it's what lets experienced readers get through far more non-fiction than they seem to have time for.

By the end you'll know the book's main argument, which chapters answer your question, and whether its style suits you. Some books you'll drop here, which is a success: you spent twenty minutes, not ten hours. The rest you'll read better, because you know where they're going.

Skip Chapters Without Guilt

Unlike a novel, most non-fiction isn't a chain where every link depends on the last. It's a collection of ideas, and some aren't for you. Read the table of contents like a menu, start with the chapters that answer your question, and skim or skip the rest.

Plenty of non-fiction books are an essay's worth of insight expanded to book length. Getting the insight efficiently isn't cheating; it's the point. Just know when you're skimming and when you're reading; our guide to reading faster covers where skimming helps and where it costs you.

Close the Book and Recall

The single most effective thing you can do comes from research on the testing effect. In a 2006 study, Henry Roediger and Jeffrey Karpicke had students read short prose passages and then either reread them or try to recall them from memory. Rereading looked better on a test five minutes later; recalling was clearly better two days later and a week later.

So end each session by closing the book and writing down, from memory, the two or three ideas that mattered most. Only then look back to check what you missed. It feels harder than highlighting, and that difficulty is what makes it work. Keep the notes somewhere permanent: a notebook, or a tracker like Parch, where you can log the session and add the note to the book in the same minute.

Review It Again, Spaced Out

Recall works best when you repeat it with gaps. In a 2013 review of ten popular study techniques, John Dunlosky and colleagues rated two as most effective: practice testing (recalling from memory) and distributed practice (spreading reviews out over time). Highlighting and rereading, the two things most readers actually do, were rated low.

You don't need flashcards. When you finish a book, look at your notes and try to recall its main ideas the next day, again a week later, and once more a month on. Each review takes a few minutes, and the ideas that survive three rounds tend to stay. Parch's custom tags let you group books by subject, so when you come back to a topic, the books you've read on it are easy to find.

Explain It to Someone

The most natural form of recall is telling someone else. Explaining a book's main idea to a friend over dinner, or writing it out in a few sentences as if for someone who hasn't read it, forces you to pull it from memory and put it in order, and it shows you straight away which parts you didn't really understand.

If there's no one to tell, a short written summary after each book does the same job. Three sentences is enough: what the book argues, the best evidence for it, and what you'll do or think differently.

Listen to the Stories, Read the Arguments

Format matters more for non-fiction than for novels. Memoirs, biographies and narrative history work beautifully as audiobooks: there's a story to carry you, and a good narrator adds to it. Dense idea-books, with tight arguments, statistics and unfamiliar terms, usually go better in print, where you can slow down, reread a paragraph and make notes.

You don't have to choose for the whole book. Listen to the narrative chapters on a walk and read the hard ones at a desk. In Parch one book can be print, ebook and audiobook at once, and each format keeps its own place. Our guide to the best audiobook speed covers how fast you can comfortably listen.

Start with Short or Narrative Non-Fiction

If dense idea-books stall you, build the habit with non-fiction that reads like a story (memoirs, biographies, narrative history) or with books short enough to finish in an afternoon. A few from our list of short books, with times at an average reading speed: We Should All Be Feminists by Chimamanda Ngozi Adichie (about 70 minutes), The Fire Next Time by James Baldwin (about two hours), A Room of One's Own by Virginia Woolf (about two hours), and Hiroshima by John Hersey (under three hours).

Finishing a few short ones builds the confidence to take on longer, denser books.

Keep a Novel Going Alongside

Don't read non-fiction exclusively; it's the fastest route to burnout. Keep a novel going too, and choose by energy: the demanding book when you're sharp, the story when you're tired.

The pairing keeps both going. The novel maintains your reading momentum, and the non-fiction gets your best attention instead of your leftovers. If keeping any reading going is the hard part, our guide to building a daily reading habit starts there.

Frequently Asked Questions

How do I remember what I read in non-fiction?

Recall it rather than reread it, and repeat that recall with gaps. At the end of each session, close the book and write down the two or three ideas that mattered most, then check. When you finish the book, review your notes and recall the main ideas a day, a week and a month later.

Does highlighting help you remember?

Not much on its own. A 2013 review of study techniques rated highlighting and rereading as low in effectiveness, and recalling from memory and spaced review as the most effective. Highlight if it helps you find passages later, but do the recall too.

Is it OK to skip chapters in a non-fiction book?

Yes. Most non-fiction is a collection of ideas rather than a single argument. Preview the book first, read the chapters that answer your question, and skip the rest.

Are audiobooks good for non-fiction?

For memoirs, biographies and narrative history, very. For dense, argument-heavy books, print is usually better, because you can slow down and reread. Many readers mix the two, listening to the story chapters and reading the hard ones.

What's a good first non-fiction book?

Something short or story-driven. We Should All Be Feminists takes about 70 minutes, and The Fire Next Time and A Room of One's Own about two hours each. Memoirs and narrative history are also easier starts than dense idea-books.

Should I take notes while reading non-fiction?

Take a few, but the notes that matter most are the ones you write after a session from memory. Summarizing what you recall does more for retention than copying passages as you go.
