Wow, thanks for all the replies so far!
Carnation, what is your original field?
Dancer, did you study library science? My lil sis is considering that (she's an English major)!
Greeko, I'm not sure which way you meant with the RARE. Did you mean that history professors are a dime a dozen and so professor position openings are rare, or that a lot of schools really need history professors? Thanks for your help!
