The list is from Steve Cunningham who interestingly frames the five books in terms of the lessons we should take away from them.
- You Need to Build Trust: Trust Agents: Using the Web to Build Influence, Improve Reputation, and Earn Trust by Chris Brogan and Julien Smith
- Turn the Bullhorn Around: The Whuffie Factor: Using the Power of Social Networks to Build Your Business by Tara Hunt
- Learn the Pillars of Social Media Success: Six Pixels of Separation: Everyone Is Connected. Connect Your Business to Everyone. by Mitch Joel
- Work Your Face Off: Crush It!: Why Now Is the Time to Cash In on Your Passion by Gary Vayberchuk
- Get Smart About the Tools: The New Community Rules: Marketing on the Social Web by Tamar Weinberg
Four of the books look pretty good, the kinds of books that have lot to say about how libraries could engage patrons in social media spaces. I have both the Mitch Joel and Tara Hunt books kicking around the house and look forward to reading them and will probably get both the Brogan and Weinberg eventually. And reviewing them all here, of course.
As for Crush It!, well, I tend to favour a bit more of a work/life balance than that book seems to advocate.
