| Abstract: | Summaries. Although nearly 400,000 books of the Library of the USSR Academy of Sciences in St. Petersburg were lost from smoke, fire and water damage during the February 15, 1988 fire, many more were saved. Two of the methods reported during a 1089 symposium and unknown outside of Russia arc described. 1 he first is dry leafcasting, i.e., a method to fill in missing parts with fibers by suction out of dust; the fibers are impregnated with a thermoplastic and, when they have, filled the holes, bound together by heat. The other is stabilizing the wet books by freezing and drying them in packages of 10-15 books at slightly elevated temperature and slightly reduced relative humidity. |
