A new book "I'm Outta Here! How coworking is making the office obsolete" is a book about the people and places that make up a workplace revolution. Written by a trio of authors, Drew Jones, Todd Sundsted, Tony Bacigalupo, the book is being published through Lulu.com an online publishing house, and is also available as an e-book.
I think this is the first book dedicated to the CoWorking movement, and its history as its happening. They also have a great website and blog to promote the book where you will find coverage of news in the CoWorking world.
