Pro tip: if you’ve read a book elsewhere, like a print copy, just tap the … button and mark the title as read in Apple Books. It will become eligible for your Year in Review
Look up the books, mark them as “Finished”, and see your stats change – very nice.
From the press release for Year in Review, the new feature in the Apple Books app:
Year in Review is available on iPhone and iPad within the Read Now tab under Top Picks to users with at least three titles marked as finished.
