First off, this book has a surprisingly large emphasis on INGOs, which was interesting to me but might not be your cup of tea if you're interested in working on domestic issues. That said, I think the information here could probably be 90% applicable to any 501c3 organization. It's a very comprehensive overview of PR/external relations, including media relations, stakeholder and public outreach, fundraising, partnerships, branding, internal comms, and strategic management.
My favorite part was Part IV, which focused on global communications and strategic management, and included case studies from India, China, Brazil, and South Africa. This might just be me, but case studies make everything better. They might be one of the few things I unconditionally love, like pizza, tacos, and inter-species animal friendships.
Where was I? Yes, as a whole, this book is pretty good. I do wish the editor had taken a page from his own book and adjusted the writing style, though. The book is incredibly academic and kinda dry, which is definitely not necessary.
