Confused about how to use Google Wave, the new Google product that combines messaging, wiki-like features and group collaboration into a single app? You’re not alone.

To clear up the confusion, we recently published Google Wave: A Complete Guide, a feature-length article that explains Wave in plain English.

Now Gina Trapani and Adam Pash have gone a step further, releasing The Complete Guide to Google Wave. The book, which is available for free online, details all of Wave’s features – and some use cases – in 8 chapters. It’s a super-handy reference if you’re still stuck on how to get the most out of Wave. Recommended!
