Yeah, all those are pretty much "must have" classics for the Lampropeltis keeper. I have had all those for many years now.
Brian Hubbs' "Common Kingsnakes" - "A Natural History of Lampropeltis getula" book is absolutely second to NONE in regards to the getula complex. It is the best, most detailed, and in-depth kingsnake book on the entire planet without exception! 
And I am not just saying this because I have a couple Outer Banks kings featured in it either. It is truly the best written kingsnake book in existence...period!
Brian spent four long years compiling this awesome publication, and it certainly shows too.
