The information presented in this book is poorly organized, outdated, and incomplete. Sadly, it's the only book dedicated to OmniMark. The best way to learn OmniMark is to go to Canada and learn from OmniMark Technologies. This book covers OmniMark version 3. OmniMark version 5.1 is out now (July 1999).
