Frequently Asked Questions
5 questions
Physical books show 7% better retention: 65% vs 58% for digital readers according to a 2023 Oxford University study of 2,000+ readers. This advantage increases when readers take handwritten notes, jumping to 89% retention with physical books vs 71% with digital.
