Recently, Pasadena City College took action to create an easier way for students to take classes without the need of purchasing expensive textbooks. Beginning during the Winter 2018 intersession, students are able to search the course catalog for classes that only use zero-cost textbooks. This applies to not only traditional classes, but also online classes. These classes will utilize only open educational resources (OER) available for free online.
