McDonnell Douglas Aircraft since 1920

[AE220]

I've been interested in this book for some time but I have a question. What's the difference between
McDonnell Douglas Aircraft since 1920
and
McDonnell Douglas Aircraft since 1920 I and II?

Also can anyone with the book give a rought idea of the eras covered in volume I and II?
