Officials with the Iowa Genealogical Society Library said that the roof of the building that houses their library partially collapsed.

The collapse happened during the first major blizzard of winter, officials said. The library at 628 East Grand Avenue in Des Moines suffered extensive damage.

Officials said that in the days before Christmas, melting snow and rain on the flat roof caused the collapse. The ceiling in a storage room, office area and parts of the library itself were damaged.

Officials said volunteers worked to cover books and equipment, including protecting "endangering irreplaceable family history volumes."
