Is there a community here for recommending textbooks to rent for class?

Because currently, I am forced to learn the subject Business Finance 381... from a Professor that seems to be an absolute idiot. For one thing, he demonstrated the flaws of democracy... by listening to the majority of his students, who said they aren't helped by a textbook, and not having a textbook assigned to his class, nor even having a designated textbook for his class, or having such a textbook available for helping to help people learn. So thus, as you can imagine, I am in the minority of students that is hurt by him listening to the majority, and I am without a viable textbook to find even at the college bookstore.

Are there communities on this site for finding appropriate books/textbooks to use?
