Back in March, I published a short list of suggested PR “must reads” by the community. It was an impressive list. Even more so when you added in the 16 comments with additional suggestions.

But, with the flurry of new “social media” (technically, they’re not all “social media” books, but I couldn’t come up with a better, broader term) books hitting the market recently (Trust Agents, Twitterville and Six Pixels of Separation, for starters), I thought we’d revisit the concept on the social side. After all, ALL PR pros need to get smarter about the social space, right?

Below is the list of suggestions from some trusted members of my community. What would you add to this list?
