One of the primary goals of the Atlas of Surveillance is to provide journalists and researchers with the data they need to do in-depth reports on law enforcement surveillance around the country. To that end, we've made our source data available, but we've also compiled this library of data sets and data projects from other organizations that informed the Atlas of Surveillance or are useful in tandem with our research.

"Using that data, along with public records and interviews [Buzzfeed has] created a searchable database of US-based taxpayer-funded entities, including tribal, local, and state police departments publicly funded university law enforcement bodies; district attorneys’ offices; and federal agencies such as the Air Force and Immigration and Customs Enforcement.
