From MOMA:
The Museum of Modern Art's conservation staff and speakers from the American Institute for Conservation Collections Emergency Response Team (AIC-CERT) will conduct a series of workshops to help the many artists and galleries whose works were affected by Hurricane Sandy. They will provide suggestions and answer questions on how to safely handle damaged paintings, drawings, books, sculptures, and other artistic and cultural materials. Visit MoMA.org for more information on this program. MoMA has also issued Immediate Response for Collections, a document offering step-by-step guidelines for dealing with artworks damaged by flooding, and we will continue to lend knowledge and support to those caring for collections affected by the storm.

Its a shame when precious works of art and documents become damaged but I suppose that to is a part of history.
