A few books got really damaged. But a larger number of books just got a bit of mold along one edge, the edge that was adjacent to the bottom side of the box. Most of these are still perfectly readable, a bit warped from dampness, and a bit discolored by mold along the edge to varying degrees.
Those of you who know how to deal with books: What's the best thing to do to these? Do I just wipe off the mold with a napkin and let them dry? Is there something I should put on them to keep the mold from spreading? Is it better to try to compress the books back into flatness while still in a humid environment, or let them dry out entirely first? Any other suggestions?
[ Some of these books I'll eventually replace. Some of them, I'm not sure if I'll find replacement copies. And there are too many of them for me to replace now, especially when I'm not living somewhere where I have space for them. ]
