"The Uniform Crime Reporting (UCR) Program has been the starting place for law enforcement executives, students of criminal justice, researchers, members of the media, and the public at large seeking information on crime in the nation. The program was conceived in 1929 by the International Association of Chiefs of Police to meet the need for reliable uniform crime statistics for the nation. In 1930, the FBI was tasked with collecting, publishing, and archiving those statistics."

"The SAC Publication Digest contains abstracts of reports produced by state Statistical Analysis Centers (SACs), with links to the full reports. These reports cover a wide array of topics and analysis approaches for criminal justice data at the state level."

"The Commission collects, analyzes, and disseminates a broad array of information on federal crime and sentencing practices. The Office of Research and Data collects data from documents submitted by the courts in each case in which a defendant is sentenced. From that data, the Commission prepares and disseminates public reports on a wide variety of sentencing issues. The Commission also uses this data in its consulting capacity to the courts, Congress, and the Executive Branch."

"NCSC is the organization courts turn to for authoritative knowledge and information, because its efforts are directed by collaborative work with the Conference of Chief Justices, the Conference of State Court Administrators, and other associations of judicial leaders."

"The mission of the National Archive of Criminal Justice Data (NACJD) is to facilitate research in criminal justice and criminology, through the preservation, enhancement, and sharing of computerized data resources; through the production of original research based on archived data; and through specialized training workshops in quantitative analysis of crime and justice data."

"The World Prison Brief is an online database providing free access to information on prison systems around the world. It is a unique resource, which supports evidence-based development of prison policy and practice globally."

An extensive list on a variety of different corrections subjects.

"Despite its widespread use, research shows that the effect of incarceration as a deterrent to crime is minimal at best, and has been diminishing for several years. Indeed, increased rates of incarceration have no demonstrated effect on violent crime and in some instances may increase crime. There are more effective ways to respond to crime—evidenced by the 19 states that recently reduced both their incarceration and crime rates.

With a few hyper-localized exceptions that require targeted attention, violent crime rates are lower today than they have been at any point over the past four decades. However, this era of public safety has been misrepresented by some media reports and public commentary concluding that violent crime increases in a few cities equal a sweeping national problem. This brief examines those erroneous conclusions about current crime trends—using both existing and original research—and describes how to avoid common pitfalls when interpreting statistics on violent crime.

"People are spending more time in prison, and the longest prison terms are getting longer.

To better understand long prison terms, we took a new approach to measuring how much time people spend in US prisons. We looked at annual snapshots of prison populations to see how long people had been in prison so far and compared those snapshots over time. This allowed us to include time served by people who are usually overlooked by more traditional methods."
