Students in an NCPTT workshop learn how to air dry books that were in a flood.

Books being prepared to air dry.

With the aftermath of Hurricane Harvey only beginning, NCPTT wants to share pertinent resources. In 2004, the Center awarded a Preservation Technology and Training grant to the University of Utah’s Marriott Library to develop a Protocol for Emergency Washing, Drying, and Sterilization of Historically Significant Books.”  The research team tested recovery protocols for flood-damaged books from the 18th through the 20th centuries to determine the most effective procedures for mass-drying or sterilizing culturally significant collections.

The study compared air drying, vacuum freeze drying, vacuum packing, drying in a Vacme press with Zorbix, and Thermal drying as methods. Additionally, two sterilization methods were reviewed: gamma radiation and sterilization with ethylene oxide.

The results of this study can be found here.
