Following extensive research and experiments, David Fischer and Thomas Duncan discovered a successful freeze-drying technique. If books with coated paper were thawed at less than 37°F. while the water was evacuated in a vacuum chamber, the would be saved. Based on his research, 3,500 damaged books (mostly with coated paper) were placed in a large vacuum chamber, owned by General Electric, for thawing and drying. This process allowed a large number of books to be treated at one time, and it was the first time books with coated paper were able to be salvaged. Nearly half of the library's damaged collection was successfullyy restored with this method.
