ANN ARBOR—The preservation of books, documents and photographs will be the focus of a special open house honoring the 20th anniversary of the University Library’s preservation division on Sept. 18. The open house will feature demonstrations and displays in the state-of-the-art conservation lab of techniques used by staff who repair and conserve thousands of books each year for the University Library. Visitors can see books being rebound, learn about the preservation of 2000 year-old papyrus and watch paper being washed. Visitors are invited to bring personal books or photos for advice on how to care for them. One of the highlights of the open house will be a demonstration of the University’s new Zeutschel Omniscan 7000 camera in the Preservation Division’s digital reformatting lab. Visitors are invited to bring with them a personal black and white photo or document (8½ by 11 inches or smaller). The camera operator will scan and print a copy to take away as a keepsake. Preservation specialists will demonstrate how digital imaging is used to capture and preserve information in books and photographs that have deteriorating paper.
