Hot off the presses!
Some people think I'm a stereotype of a nerd 🤓, but isn't that kind of a cliché?

Let's talk about how "stereotype" & "cliché" were invented by the printing press.

Movable type depended on typesetters putting little letter blocks (a 'sort' or 'type') in 'forms'.

My freshly unwrapped copy of Richard's book.

My copy arrived today! I look forward to reading it. Thank you!

Math at Project Gutenberg

Project Gutenberg has long had an interest in mathematics, perhaps because of its timelessness. This interest has been expressed in many ways, though perhaps some of them were misguided in retrospect.

Thanks, I'll check it out. I really liked your talk on Pop Bibliography, by the way.

Does the Winterthur have bookmark collections? I would be interested to hear about those.

Congratulations!

Thank you!!

Typos Have Plagued Us for Centuries. Just Ask the Publishers Who Printed the Seventh Commandment as 'Thou Shalt Commit Adultery' in 1631 A new exhibition at Yale Library explores the history of typos across five centuries. Visitors will see corrections that were listed inside copies of works by James Joyce, Upton Sinclair and Nicolaus ...

A history of typos will soon go on display at Yale: "With this exhibition, we wanted to share ways in which even small corrections can reshape meaning and authority." www.smithsonianmag.com/smart-news/t...

It is curious how similar this is to the reasons given by the former editors of MLQ (Wiley).

I attended yesterday a magnificent talk by Asa Mittman on medieval monsters. At some point he effusively recommended your previous book for the views past the period he covered.

Congratulations! Is there a way of getting a copy of the thesis?

This is very timely. I've been lately thinking about what I call the ephemera of mathematical research. All those bits of knowledge we collect informally and easily get lost.
