Beginning in 2006, the Society of American Archivists (SAA) has designated May 1 as MayDay for saving our archives from the consequences of disaster; largely in response to the growing number of hurricanes, tornadoes, floods and fires in recent years that have damaged or threatened archival collections in cultural institutions.
There are numerous activities and ideas available to participate in MayDay. Many ideas can be applied to personal collections. Since May 1st falls on a Saturday this year, a link to some helpful information will have to suffice. The Library of Congress has a great website for preserving treasures after the disaster. Check it out and be prepared!
