Campbell Systematic Reviews is the peer-reviewed online monograph series of systematic reviews prepared under the editorial control of the Campbell Collaboration. Campbell systematic reviews follow structured guidelines and standards for summarizing the international research evidence on the effects of interventions in crime and justice, education, international development, and social welfare.

Campbell Systematic Reviews is published bimonthly. Issues contain reviews only, not protocols or title registration documents. These may be retrieved from The Campbell Library.
