When my amazing mother-in-law (and site proofreader!) recently came for a visit, I saw something new: some colored tape on the spine of her library book with a date on it. Though it was the arrival date for a intralibrary request, I would use this idea and put the due date on there. Remember when there were conveniently placed stamps inside the books and you didn’t have to look at your app to figure out what books to renew or return? (Or what ones are from the library if you have kids with lots of books!) This makes it even easier – you don’t even have to open the book!
