Want a good way of testing your disaster recovery planning? A flood! As the CBC reported, "A broken water pipe flooded the main building of Library and Archives Canada in Ottawa early Tuesday morning, closing the building and causing a small amount of damage to some books." You can read the whole story whose headline (Flood shuts Canada's national archives) says it all.
I do find it interesting that the CBC uses the phrase, national archives. In terms of institutional age, the national archives goes back to the 1870s whereas Canada only acquired a national library in the middle of the twentieth century. Even more interesting is that the article only refers to books being damaged, not archival materials per se.
That said, it could have been so much worse. One has only to think of the terrible library flood damage that occurred in Florence in 1966.
