Query: Good book that continues

This book is a great starter book for those learning Linux and those of us that know enough to be dangerous. The book is easy to understand. The best part is it continues to be written! With access to the book online, you will find the whole book with additional chapters and articles. This makes it easy to look up information when you are away from the book. I can leave the book at home, and look up info from work. There are several subjects that could be expanded upon or are not mentioned, but who knows, it may become available online.
