Considering a career as a librarian?

I have a BA double major in History and Religion. I am not finding much with these majors job wise and I'm considering going to graduate school. However, the masters program would have to be online and I'm considering getting my Masters of LIbrary and Information Sciences degree to become a professional academic librarian. My problem is my undergrad GPA is low 2.5 but I got a good GRE score over 1000. Is it possible for me to be accepted into an accredited online program? What do you think about this career choice?
