In 1929, the sixth edition of Gregg Shorthand was published. This series, Gregg Shorthand Anniversary, was much easier than before. No real changes were made in the basic principles of the system, but it changed according to the frequency of the words used at the time. No longer was it necessary to have a quick phrase ready for when someone said “I am in receipt of your esteemed favor on the 4th inst.” The manual was rearranged from twenty lessons into twelve chapters, divided by thirty-six units. The word-signs were now known as brief forms. Most of the brief forms and prefixes mentioned here were removed due to lack of frequency. The following synopsis of Anniversary Gregg Shorthand was in Gregg Speed Building for Colleges.
Anniversary Gregg Shorthand has 318 Brief forms with 140 Special Forms, which were simply outlines that one could employ that followed the abbreviation principle.
Though this series was well simplified from the first and second editions, it still was difficult for the student due to the moderate memory load. This series was meant mostly for the well-trained court reporters and could be employed to reach astronomical speeds for that day.
At the end of this series’s run, John Robert Gregg passed away. Just one year after his death, the Gregg Publishing Company was no more, having been purchased by McGraw-Hill around 1949. The Gregg Writer—a magazine published for secretaries, typists, and stenographers—was deleted as soon as Anniversary Shorthand became nonstandard by the Gregg division. It was succeeded by the magazine—which used the seventh edition of Gregg shorthand, the Simplified Series—Today’s Secretary.
