Archaeology Textbook


Salvete omnes!
How up to date do archaeology textbooks have to be?
I'm applying to an archaeology summer program in France next year. Though there are no explicit pre-reqs and reading lists, I thought being more prepared for it would be better. I'm learning from a 1991 text, "Archaeology Theories Methods and Practice" by Colin Renfrew and Paul Bahn. The book is an old Christmas gift to my family, and I used it because it's the only one I have.
