As we get ready for Lotusphere 2010, I thought I would make you aware of a couple of books that have been published recently and I recommend you buy.
First, there's IBM Lotus Connections 2.5: Planning and Implementing Social Software For Your Enterprise. This book was written by a set of Lotus Connections experts ranging from product managers, developers, and services specialists. It covers everything from business value of social software, to adoption of social software in the enterprise, to deploying and customizing Lotus Connections v2.5. I was the technical editor for this book, so you know the content is good. 
Second, there's Web 2.0 and Social Networking for the Enterprise by Joey Bernal. This book also has a foreword by Jeff Schick and you may remember that I gave away a copy recently at the Tri-State LUG. Joey and I worked together under the same manager when I used to work in the IBM Software Services team. He asked me to be a technical reviewer for chapters 1 and 4. Chapter 1 is around definitions on Web 2.0 and Social Networking, while chapter 4 is about Social Software for the Enterprise.
Last, there's The Social Factor which has a page dedicated to me! 
The author of the book, María Azua, interviewed me to learn more about my story of Why I Love Blogs. She liked my story so much that she included it in page 50 of the book. My former teammate, Laurisa Rodriguez, wrote a chapter for this book. ComputerWorld lists this book as one of the 5 must-read books for social media marketing.
Enjoy!
