Crisis, Tragedy and Recovery network (CTRnet), is a digital library network for providing a range of services relating to different kind of tragic events. Through this digital library, we collect and archive different types of CTR related information such as Web sites, videos, blogs and tweets.  Various collections about school shootings and natural disasters have been developed from collaboration with the Internet Archive.  Please click an image below to visit the collections. The complete list of our web and tweet collection names can be found here

We provide services such as visualization, searching and browsing of the data. We hope that these services could help communities and stakeholders as they heal and recover from various tragic events. We also hope that our data is useful for researchers who investigate the various aspects of disasters.
