I just downloaded France 2013 and was amazed to find nothing about Corsica! Does RS not have any info on Corsica?
RS does not aim to cover any country comprehensively. For that, you have to go to Lonely Planet or something else.
Just surprised as most other travel books about France cover it. All of the RS books I have had in the past cover quite a bit of the country in the title.
Just a comment. Rick Steve's Italy does not include Sicily or Sardinia either; and Rick Steve's Great Britain does not cover the Channel Islands or the Isle of Mann. So, it does not surprise me that his France book does not include Corsica. They are not as comprehensive as some other guides but good for what they give you.
I had the same problem with the RS Spain book when I was traveling only to northern Spain. The book had not one word about any of the places I was going. I ended up returning it to the bookstore and picking up something else that was more comprehensive.
