And if you work with punctuation for a living in any way, and have access to the BBC iplayer, have a listen here for a programme on stenography. The section on Hansard (which reports what went on in Parliament) is enlightening.
"As courts around the world replace human stenographers with digital recording systems, Michael Rosen explores the ancient art of stenography. Michael looks at the work Charles Dickens did in London courts around 1830, and asks how his career as a shorthand reporter influenced his work. He investigates the mysteries of modern stenograph machines, and talks to people who operate them and to a leading barrister about the different ways we record words spoken in trials and other official proceedings."
