Please note that this screencast series was produced during a short period of time, and may contain parts that appear (and are!) unprepared. Sorry about this. Also, the View version used is in development stage and still contains some bugs. That's life in the front line!

Currently there is no official documentation for the Views 3 module, but you can always read more about Views on the Views project page at drupal.org. If you want to help out with making Views better, please consider answering support questions in the Views issue queue!
