In addition to maintaining its own databases, the DRC is a repository for materials collected by other agencies and researchers. The E. L. Quarantelli Resource Collection contains the world’s most complete collection of disaster-related material, with a particular emphasis on the social and behavioral science aspects of disasters. Now numbering more than 125,000 items, the Collection is open to interested scholars and agencies involved in disaster research. This premier collection includes documents and publications not readily available elsewhere, and acquisition priorities include the collection of rare or otherwise unavailable items and documents. The Center also maintains its own book, monograph, and report series.
