Not a libriarian but have some tips I could share lol! You could get some plastic clamps that hardware stores sell & put those on the ends to help hold it tightly together while youre sanding! I'd put a piece of folded fabric or paper towels between the clip and the cover so it doesn't scratch it. I use that method when I'm doing some of the "old book crafts" I make with damaged books & it works really well! Only time I damaged a book using this method was user error, I pulled on the clip before I had it fully opened, so keep that in mind if you try it since yours arent being repurposed! For the sand paper & shaky hands -- very very very fine grit sand paper so you don't over do it! Can attach the sandpaper to the handle part of a small cleaning sponge so you can grip it better. I do this for crafts as well lol! I'm not great at describing what things look like lol but, looks like this! I just take the sponge off & add the sandpaper, bet it would help!
