In addition to meeting minutes and project correspondence, this series contains extensive research material gathered by the organization, including reports and booklets from similar organizations, news articles, and copies of domestic violence law. A journal with meeting notes and a phone log, documenting calls and help requests receieved by the IV Project, completes the series.
