The Theory of Change library is an on-going project of the Theory of Change Community, with the long-term goal of being a comprehensive resource for all things TOC – background, how-to, books and articles, case studies and examples, videos, and presentations.

We believe that to have a full understanding of how and when to use Theory of Change methodology, the library needs to also contain materials about different outcomes-based methods. To that end, we welcome articles and publications that review other methods, and particularly any comparative studies.
