The document summarizes the It Takes a Village (ITAV) project, which was funded by IMLS to study models of open source software sustainability. ITAV conducted a survey of 27 open source programs and held a two-day forum. Key findings were that sustainability has many facets that programs move through in cyclical phases. ITAV developed a guidebook of best practices to help programs at different stages. The guidebook has been useful for projects in evaluating their sustainability. Next steps discussed include continuing the annual forum and potential new services to further support open source communities.
