RAF Evaders publ 09 and RAF Evaders publ 12

[phasselgren]

Hi,
There are two books by Oliver Clutton-Brock with the main title RAF Evaders:

RAF Evaders: The Complete Story of RAF Escapees and their Escape Lines, Western Europe, 1940-1945 (published 2009)

Raf Evaders: The Comprehensive Story of Thousands of Escapers and Their Escape Lines, Western Europe, 1940-1945 (Published 2012)</SPAN>

What are the main differences? I see that the book from 09 has a complete list of evaders but it is not mentioned in the later book.

Thanks in advance
Peter
