Found this on the Typosphere blog. Seems to focus primarily on German typewriters; not sure because I'm still trying to figure out how to navigate it. Seems to have a lot of information on it.
“Don’t be too harsh to these poems until they’re typed. I always think typescript lends some sort of certainty: at least if the things are bad then, they appear to be bad with conviction.” ~ Dylan Thomas
I got an e-mail about this from the organisers of the website. They want to charge a subscription to be able to view it. Most of the info that they present is available for free on other websites, so why pay ?
