Precautions

• Books that are to be frozen should be kept closed to minimize warping.

• Books with coated paper should not be allowed to dry out until they are interleaved or frozen.  It is better to allow them to stay wet if they cannot be stabilized promptly.

• Do not empty cardboard boxes if they are very wet.  Freeze as is.

• Always remember that reducing the cost of future restoration must be one of the top priorities of the salvage operation.

• No untrained person should ever be allowed to wash water-damaged materials.

• Never wash books if time is critical.

• Never wash material that contains water soluble materials such as non-permanent ink, water colors, tempura, etc.
