A special supplement, Collective Insights on Collective Impact, offers nine articles from leading practitioners, funders, and thought leaders in the collective impact field, curated and funded by the Collective Impact Forum. These include two articles of particular interest to those working on youth issues, written by the Forum for Youth Investment, about aligning multiple collective impact initiatives in a community (p. 15), and how government policies can be crafted to enhance, rather than impede, collective impact efforts (p. 22).
