Systematic reviews and meta-analysis are techniques for synthesizing primary empirical studies to produce a summary of effects. To facilitate this goal, the Campbell Collaboration (C2) supports reviews within the disciplines of crime and justice, education, international development, and social welfare. At the annual Campbell Colloquium, experts on systematic review and meta-analysis provide introductory and advanced methodological training to researchers and practitioners. The C2 has filmed the training sessions and offers access to these videos, free of charge, on their website. The purpose of this article is to provide some background on the C2 and to introduce the presentations available on their website. (Contains 2 tables and 3 notes.)
