The More You Know
If you have a water damaged book, put it in the freezer. Services exist to repair them, apparently.
Of course, our water damaged books are books, well, we put in the basement because they were deemed unworthy to take up precious shelf real estate. So they’re just a mess to clean up.
That said, there are some nice books elsewhere I’d cry if they got water damaged, so now it’s good to know what to do if that happened.
