I'm learning a lot, and getting many good reminders about what I already know, by reading smart writers' books about Communications. Here are the links to some that I recently reviewed:
The Nonprofit Marketing Guide
Robin Hood Marketing
Strategic Communications for Nonprofit Organizations
How to Find a Job on LinkedIn...
Many of these authors, and other smart people, are giving good advice every day on Twitter. Follow me @DennisFischman and check out my Communications list.
