Once in a while a copy comes up on E-Bay or at abebooks.com.
If you're familiar at all with this series, the shorthand book follows the same format and "tone", with lots of suggestions for self-study techniques.
There's a book with the same title about Pitman shorthand, so if you're looking for this one be sure you check the authors and/or description.
Obviously because of the date, the system is the Anniversary system.
