“If I don’t like the cover, I won’t photograph it and put it on my feed,” says Femke Brull, a “bookstagramer” who runs @booksfemme. While she won’t avoid promoting a loved, if less-attractive book, she opts for a snap of the title page instead – even if it is less memorable than a beautifully covered counterpart. And she will “pay extra” for what she considers a better-looking edition.
