The document begins with a list and description of eight publications recommended for every advocate. The next section lists resources related to general firearms violence, including firearms homicide, firearms homicide related to domestic violence, firearms homicide in the workplace, firearms suicide, firearms deaths of children, and nonfatal injuries related to firearms. Other sections cover the costs of firearms violence, gun-related crime, firearms ownership, weapons carrying, the use of guns in self-defense, gun buybacks, studies of self-defense by supporters of citizen gun ownership, licensed dealers, and marketing firearms to women and youth. Each citation includes bibliographic information a summary, cost, and source. Appended lists of organizations and agencies and discussion of how to understand and use statistics
