On Rereading

10 Jan 2026·2 min read

There’s a particular kind of impatience that treats every book as a box to be checked. Finish it, shelve it, move to the next. I understand the impulse — there is so much to read, and one life is short — but I’ve started to think it gets the economics backwards.

A book you’ve read once is a book you’ve met. A book you’ve read twice is a book you know. The information content of a second reading is lower — you already know what happens — but the comprehension content is often higher, because you’re no longer spending attention on plot. You can watch the structure instead of the story. You notice what the writer set up on page twelve that pays off on page two hundred.

I used to feel guilty about rereading, as though it were a failure to keep up. Now I think of it as the difference between visiting a city and living there for a season. The tourist sees the landmarks. The resident learns which street is quiet at 6am and which café has bad coffee but the only good light.¹

Some books resist this entirely — they are built for a single, forward-moving reveal, and rereading them mostly confirms you already know the twist. But the ones worth keeping tend to be the opposite: books that get better once suspense is off the table, because suspense was never the point.

I don’t have a rule for which books earn a second reading. I just notice, a year or two later, which ones I’m still thinking about — and those are usually the ones I go back to.

This is, I think, also the best argument for keeping a notebook. Notes are how you reread a year without living it twice. ↑
