Contact the National Center for Non-profit Boards, in Washington, DC. They publish a specialized series of pamphlets on myriad non-profit issues. All of those I have used were excellent. They also produce general texts on the subject. Mary Case and I are both among museum people who have attended one or more of their training programs as well. Startegic management is not a subject I take to naturally, but I benefitted enormously. No, this is not an ad for NCNB, but I do want colleagues to know that its services have won me over through a variety of experiences with them.
