Briefcase is powered by sourceAFRICA, the continent's largest repository of documents from investigative journalists and civc watchdogs.

sourceAFRICA is powered by DocumentCloud, but includes a new user interface that makes it easier for journalists to create project micro-sites and document collections for their investigations.
