At my Gregg site, http://gregg.angelfishy.net/, I have scanned the book, 5,000 Most-Used Shorthand Forms, which is like a more concise dictionary of Anniversary Gregg Shorthand than the Dictionary.
Also, I have posted the notes of a 1940’s Surrogate Court Reporter, Sklarew, which are in heavily abbreviated Gregg Shorthand. With that is its transcription.
Also, I have posted Charles Swem’s article on the use of shortcuts in Gregg Shorthand. It features many valuable curtailling principles and a few examples of each. They are great, like “complained of pain the leg” is just “kpal”. Neat stuff.
Check it out!
