The Social Media Bible by Lon Safko and David K. Brake is the book to buy.
The information found in The Social Media Bible is comprehensive, timely, and practical. It provides the historical background of social media as well as how to use social media as a strategy in your marketing plan. It describes what each social media tool is, how it can be used, what other applications work with it, who uses it, and even gives suggestions on who SHOULD use it. I’ve read just about every other book on social media and none of them are as complete as this one.
As well as being an essential resource for everyone involved in marketing, PR, and business, this could well be used as a textbook for college classes in social media.
To keep the information timely, the authors have included a link and log-in information for purchasers to access up-to-date information.
