Superior, WI (Northland's NewsCenter)---Meanwhile, restoration to University of Wisconsin Superior's library books damaged in the flood at the Jim Dan Hill library will be a lengthy process.
About 100,000 books were saturated by flood waters.
About 44,000 of those books were determined to be un-salvageable and have been recycled.
Campus officials are now sending books that were on the top shelves when the flood hit to be freeze dried at a facility in Texas.
So far, campus officials have received about ten boxes back, and say the results are not as good as they had hoped.
The freeze dry process takes about three weeks.
"They bring the books to a certain temperature, and the water turns into vapor and it's sucked out by a vacuum, and then they freeze it again," Faith Hensrud, UWS Provost said. "They keep repeating the process."
Compact bookshelves for the library's basement have been ordered and are expected to arrive in the next few weeks.
