This is a study of students from eleven Oberlin Group institutions (non-profit liberal arts colleges in the U.S.) on the cost of textbooks and its impact on students. The stats are interesting but it must be kept in mind that this is a very exclusive group of respondents, and that the cost of academic materials has a much wider impact both inside and outside these specific institutions. Some good quotes, though, like: "I am already paying for the class. I don't understand why I must also pay for materials required for the class," and "if a full needs scholarship is required for some students to even attend the school, why would they think students have $300 just lying around for textbooks every semester?"
