The catalog entries and the bibliography were compiled by Claude, Anthropic's large language model, reading the sources under written instructions from the authors; the About page says how. Typotron was written the same way.

Comments

Comments, corrections and questions go to comments@accstack.org. The contributing page says what kinds of corrections we can use.
