From NACDL Press Release: 
NACDL is pleased to offer, as a resource for its members 
and as a service to the public, a collection of individual downloadable 
documents that summarize for each U.S. state the key doctrines and 
leading court rulings setting forth constitutional and statutory limits 
on lengthy imprisonment terms and other extreme (non-capital) sentences.
 The resource – Excessive Sentencing: NACDL’s Proportionality Litigation
 Project — is available at this link
NACDL President Steven D. Benjamin said: “The United States now leads
 the world in incarceration, with more than 2.2 million people behind 
bars, as a result of overcriminalization and excessive sentencing. 
NACDL’s Excessive Sentencing Project being launched today is the type of
 resource for practitioners, judges, policy advocates, and the general 
public that embodies NACDL’s tireless work to fulfill its mission. The 
tools provided in this expansive online resource will be deployed to 
improve America’s criminal justice system and will result in more 
humane, rational and proportional sentencing of those convicted of a 
crime.”
