I released Corzinair on May 31, 2006. The design was based on IBM Selectric typewriter fonts from the 1960s. I wanted to capture the wide, squarish forms and rugged serifs that were typical of those typefaces, while adapting them for digital use. The family was issued in three weights—Regular, Bold, and Italic—and included small caps. In the original release, the small caps were provided as an OpenType feature, but in 2012 I split them into separate fonts. At the time, support for OpenType small caps was limited, and it was easier for designers to access them as a distinct font in the menu, especially on the web.

On June 5, 2021, I updated Corzinair. The ellipsis was narrowed, accent kern pairs for small caps were corrected, and prime symbols were added at Unicode 2032 and 2033. I expanded the OpenType fractions feature to handle longer numerators and denominators, such as 13/64 or 199/200. I also lowered the inverse question and exclamation marks, refined outlines to fix curve errors that could cause rendering issues, and removed deprecated characters like L with dot and E with breve. On October 25, 2024, I made a minor adjustment to the style names so they would appear in the correct order in menus.

I never saw it in use, and in hindsight I think of it as a serviceable but unremarkable text face. I did reuse its outlines as the basis for Antihistory, where it took on a more distinctive distressed treatment.
