Would a beatnik be using a typewriter? I was a young person back then and most young folks didn't use them except maybe in upper-class schools, for college term papers, and office work. And it's harder to imagine a beatnik or hippie using one. You might need to include an explanation of why they are using it.

It depends on how much “graphic” and how much “novel” the result: if the typewritten text is visually framed, it shouldn’t clash with the rest.
If that is the case, I would go for an accurate rendition either historically (which model of typewriter?) and/or visually (a “worn out” face, like http://www.fontfont.com/fonts/trixie).
If the lines (pun intended) between the different kind of text are more blurred, you could use either a classic text face with a monospaced cut (like Century) or a proportionally spaced typewriter face (like the ones suggested in the aforelinked thread or http://www.fontsquirrel.com/fonts/lekton).
About the text faces you mention, I’m most familiar with Perpetua, and I wouldn’t recommend it, finding it a bit “frail” and maybe even pretentious.

On The Road was written on a Underwood Typewriter - Beat writers used typewriters. Dafont has many typewriter fonts - some quite good.

Thank you very much for your answers and for pointing me to the older typewriter-discussion. I'll take a closer look at Triplicate.

@ James: they did use typewriters – but also a lot of handwriting. I'm reluctant to post text and illustrations from the book, as it is not yet approved, but I can share with you a little piece of sixties typewriting: several little notes like this one, "just left - will be back later"-sort of notes, survived all these years and I feature some of them in the book. They feels like text messages from 50 years ago.
@ riccard0: yes. The lines are blurred – and the texts not always visually separated. Century – that might work!

Thanks again.

I agree. I'm just saying it's not like today when everyone has a computer. Many folks didn't even own a typewriter. I was the editor of a newsletter in the 1970s and almost all submissions were handwritten.

I'm not saying that typewriting is a bad idea. I'm just saying that you might want to mention why a beatnik is using one.

The Last Whole Earth Catalog (1971) was assembled using photocopies and IBM Selectric type.
What typefaces best approximate the quality of “golf ball” typography?
I would suggest my Brown, for its patina of distress, although metrically it is consistent and without bounce.

@ James, they did a lot of writing in her "group". They published a magazine.
And both her parents were writers. You mentioned social class, and when they met in the 1940, her mother, who came from a middle class family, owned a typewriter, while her father, coming from a working class background, didn't. Her's was an Erica/Erika – I know that.
@ Nick – I like it Brown. It's has this slight vintage-tint. I like it. And nice story about WEC.
It's hard to make the typewriter-/monospace/slab work with a serif, so I think it must be a sans. Brown could mix nicely, I think. If anything, perhaps I could use something a little more ...casual, perhaps. But it is a good suggestion.

Sounds good.

Incidentally I've got a bunch of old ones that belonged to my dad, who did some writing. Nothing fancy, this is an old Royal still in it's carrying case.
