Open Educational Resources for Typography (OERT) is a project aimed at everyone who wishes to broaden their knowledge of typography: students, teachers, or individuals interested in the subject. This project is built upon the course material prepared by Cátedra Cosgaya (FADU / UBA), a set of booklets began to be produced in 1994, and it is currently organized into three sections: theoretical, historical, and practical. The project aims at expanding, updating, and editing the current material in Spanish, to translate it into English, and to publish it online under a Creative Commons Attribution Share Alike license.
