The descriptions are taken from the font files. Book Antiqua, Century Gothic, Arial, New Century Schoolbook, Bookman Antiqua, Times New Roman were designed to be drop-in replacements for the “Laserwriter 35” fonts from Adobe/Linotype that had become ubiquitous in 90s typography. The Microsoft-Monotype deal was one that the Monotype people were justifiably ashamed of, but also kept the company from bankruptcy. Ironically, in the twenty-first century, an era of consolidation unified longtime rivals Monotype and Linotype (along with Agfa and ITC) into a single entity.
The most interesting of the faces of this project, to my mind, is Century Gothic. It takes Twentieth Century (itself a knock-off of Futura), and modifies it to fit the dimensions of Avant-Garde and ends up with a design that’s neither Futura nor Avant-Garde but its own thing.
