Zeppelin 5-engine giants

[Travis]

Hi, i'm new to this forum, but lately have been trying to find info on these aircraft. I've seen a photo or two in my Janes book, but was wondering if anyone knew of any other resource for me to find anything else about them. Any and every bit of help would be greatly appreciated. Thanks

there is a book about the Hindenberg,
but apparently when a Zeppelin first bombed England one on the crew fell down through the roof of Nunnary and fell onto a bed just vacated by a nun!

Squadron/Signal 'German Bomber of WW1 In Action' and Haddow & Grosz 'The german Giants - The German R-Planes 1914-1918' are both good sources
