Scope and aims

The Campbell Library Methods Series supports the production of high quality systematic reviews by providing a policy and guidance on methods to authors and editors, as well as space for discussion of new and emerging methods.

The series comprises three sub-series:

  • Methods Policy Notes: Current Campbell Collaboration policy on specific methods for use in Campbell systematic reviews of intervention effects
  • Methods Guides: Guides on how to implement specific systematic review methods
  • Methods Discussion Papers: New or innovative ideas currently in development in the field of methodology. These papers are intended for discussion and do not represent official policy or guidance

Policy Notes and Guides are commissioned by the Campbell Methods Group. Discussion Papers may be submitted for consideration.
