Orthodox Herbertarian was created in 2009, painstakingly traced from scans of the typeface that was used on the American Ace Editions (Published by The Berkley Publishing Group) of Dune and many other Frank Herbert books (Such as Whipping Star and The Jesus Incident) for around a decade, from the early 70s through to the early 80s.
I've uploaded it to the web as a TrueType Font for anyone to download. You can find it here: http://dune.dribble-sponge.co.uk/dunefont/OrthodoxHerbertarian.ttf
There aren't any numbers, but please feel free to use it for anything you like. If you get copyright notification, please ignore it - it's there by accident!
Thanks for looking, it's great to keep seeing it get used!
