I'm a total typography nerd, one of my early jobs was copy-editor at a newspaper (I know, hard to believe, my posts are shockingly riddled with typos and errors, but it's true!) and one of my favourite things to do was watch the page designers put together the days editions.
Anyway, I was helping daughter run down sources for a school project, and we came across these two wee short documentaries.
The first is a wee movie about the old Fleet Street presses for the Telegraph in London, used right up until the 80's, which is really cool. It runs about 6 minutes
The other is a 20 minute documentary from Penguin that talks to lots of their type designers about fonts, type design, book design, etc. It's a bit cheesy, but I enjoyed it.
