Take regular newspapers and insert it in between the pages of the offending books. Don't use the slick ads, just the newspaper. Then put the books in an airtight container like a plastic tub. Inside the tub put a liberal amount of cheap (clean!) kitty litter. Set the books on top of the litter. Crumble up more newspaper and put it inside the tub, too. Seal the lid and leave the books in the tub and forget about them. When you find them again, the smell should be pretty much gone. This works on mildew and smoke smell in paperback books.
Good luck.
