There are thousands of books on general marketing, thousands on personal selling, thousands on advertising, and hundreds on PR. There are only a handful of books on word of mouth, which is more powerful than all the other media put together! Word of mouth is so powerful that anything you learn about it that works for you can multiply your sales. On those grounds alone, you should read every book available on word-of-mouth marketing. There aren’t that many. There will be more. I’ll post them on our website, www.mnav.com, I applaud my fellow authors and hope that all of our work synergizes one another’s.
