I am looking into learning shorthand. Actually this is something that I need and want to do in order to excel in my career. I have done quite a bit of research on here today and have decided that Greggs Shorthand Diamond Jubilee is the one for me. Now I need to buy a book to start teaching myself and know I need an introductory book. I have looked on Ebay however it doesn’t specify introductory versus advanced. Are any of those books okay for me to buy? Is there a particular year of publication that I should be looking for? I saw 1971 and 1973. Any help on this is much appreciated.
