The women's counterpart to the ATP Rulebook. For the professional woman player, this book is the governing text on registration, commitment obligations, discipline, prize money and rankings. Its rules are amended, altered or rescinded by the WTA itself under its internal constitution.
This book runs to five times the length of the ATP Rulebook because its detailed appendices — including points tables, tournament requirements and forms — are all contained within the same volume.
