The Gregg Group was founded 22 May 2004, prompted by the lack of online shorthand resources. As the primary use for shorthand — business and legal recording — has waned in recent decades, we generally acclaim the skill as a hobby or personal tool. The purpose of the group is to promote the use of Gregg systems of shorthand by providing advice to beginners, support for students, and an association of users of this efficient, attractive, and enjoyable method of writing.
Series 90 version has an Expert textbook that is quite good, and probably easier to obtain than the older versions. GREGG EXPERT SPEEDBUILDING, SERIES 90, Zoubek, ISBN#: 0-07-073077-6, 1985 is the last printing.
