The Free Expression Policy Project has a comprehensive report on free expression in arts funding. “The report includes candid interviews with agency officials regarding funding disputes, political accountability, and most important, ways of reaching out to communities and opening up dialogue about challenging or provocative art. The report also contains extensive background on the “funding wars” of the 1990s, illustrations, and two appendices summarizing free expression statements and policies among all state arts agencies and a random sample of local agencies.”
