The biggest problem with this field is that most undergraduate-level teachers really don't have the passion required to research free replacements for the textbooks recommended to them by the publishers associated with the university. I think students in each faculty should rally together and really push this point and work with the professors to find alternatives to 200$ textbooks.. The financial strain that textbook publishers place on students for profit inhibits the learning that their textbooks are supposed to stimulate... That's the big irony.
