The Complete Guide to Google Wave is a collaborative user manual for Google Wave written and edited by Gina Trapani with Adam Pash.
"This guide's web site launched October 31st, 2009, exactly one month after the Google Wave preview became available to a limited number of users. At launch, the guide contained eight fully-written chapters and two appendices (about 90 pages printed).
However, like Google Wave, this guide is an unfinished work in progress. With the help of volunteer contributors, this guide's contents will be written, rewritten, and refined in public on completewaveguide.com, as Google Wave changes and improves and rolls out to more users."
