Research Clearinghouse:

Beyond producing original research, the Prison Policy Initiative edits several databases to empower activists, journalists, and policymakers to shape effective criminal justice policy. This page contains links to virtually all the empirical criminal justice research available online, organized by category and publication date. If you know what you are looking for, you may also search the database. We also have an email newsletter (at right) for new research clearinghouse updates.
