You might want to check the archives of CoOL--it's an immensely helpful
site. Re: mildew and books, it says "mildew: A growth caused by
micro-organisms, whose spores, in a moist, warm environment, become molds.
They derive their food from the substance on which they form, e.g., the
materials of a book. During their growth they produce citric, gluconic,
oxalic, or other organic acids, that can damage paper, leather, cloth, etc.
They also at times produce color bodies, leading to staining which is
difficult to remove.
In counteracting mildew, every part of the affected book must be treated
with the inhibitor most suited for it. The best preventatives, however, are
thorough
cleanliness, sunlight, dry circulating air, and relatively low temperature.
