Very interesting links here.
Kinda bumping on old thread but if you are still looking for books, whatever they have some here:
http://www.africanhuntermagazines.com/
Apparently they have changed distribution from Zimbabwe to the US and the shipping is better (only time will really tell).
Good luck. Hunting in Africa is really a thing to have on the list of things to do before you die (doubt I will ever get to).
