Teach Yourself Gregg?

Being a former Pitman student, I have noted that the Pitman people had quite a bit of success with a series of books called Teach Yourself Pitman; one could choose either Pitman New Era or Pitman 2000.

The teaching methods were exactly suited for self-instruction; other manuals, designed for classroom instruction, really don't cut the mustard in this endeavor.

My question is--was there ever a Teach Yourself Gregg series? It seems that a lot of users of this forum have to struggle unnecessarily because they're using classroom materials.
