Access to the Campbell Collaboration site has been enabled in Library OneSearch. The resource is free to access, so access is unrestricted on-campus and off-campus. The resource is described as follows:
The Campbell Collaboration is an international research network that produces and disseminates systematic review on the effects of interventions in the social and behavioural sciences. It produces reviews in the areas of Crime and Justice, Education, International Development, and Social Welfare. Coverage is international, but research tends to be more focused on first world countries. The Campbell Library part of the site can be searched to find full text systematic review articles, policy papers, and research methods papers, which can be downloaded for free as a zip file.
