You might be able to borrow a copy of the text from another OhioLINK library [search the OhioLINK Catalog], but don’t count on it. Many textbooks are required by professors at other colleges and universities, so you’ll have competition from students in your class at Oberlin and in courses around the state.
You may have better luck finding an OhioLINK copy to borrow if you’re looking for a book that is needed for a humanities or social sciences course, whose course content is more unique to Oberlin. Consider, after all, that all chemistry students throughout the state must take organic chemistry, just as all physics majors will learn fundamentals of mechanics and relativity, and you’ll understand why basic science texts can be difficult to borrow during certain periods of the semester.
So… buy the text! And some highlighters. Make it your own. It's a good investment in your own education.
