Research Library:

Our mission is to empower activists, journalists, and policymakers to shape effective criminal justice policy, so we go beyond our original reports and analyses to curate a database of virtually all the empirical criminal justice research available online.

Tips: If you know what you are looking for, you may also search the database. We also have an email newsletter (at right)(at bottom) for new research library updates.
