Resources for women and gender studies

So, I am taking my first women and gender studies course at my college next semester and while I am really excited to take the course, I am also a little nervous. I have not had the opportunity to read a lot of feminist literature (My local library does not carry most of the books nor does the local bookstore) and I am afraid that I am going to go into the class and look like a fool because I haven’t read most of these books. I also do not know a lot of where to find feminist literature, or many of the titles of good feminist literature if I had. I was given full frontal feminism as a christmas gift and I am very much enjoying reading it, but I was wondering if any of you had any more ideas of books that I could look for and maybe where to obtain them at a reasonable price?
